| N,N',N'-Trimethylethylendiamin-substituierte Phosphor(III)-Verbindungen und deren Oxidation zu Derivaten mit tetra-und pentakoordiniertem Phosphor N,N',N'-Trim ethylethylenediam ine-Substituted Phosphorus(III) Com pounds and their Oxidation to Derivatives with Four-and Five-Coordinated Phosphorus  | | | Abstract
| A study was made o f the intramolecular donor-acceptor interaction in N ,N',N'-trim ethyl-ethylenediamine-substituted phosphorus com pounds, involving A3-, A4-and A5-phosphorus atom s, as a function o f the nature o f the substituents at phosphorus. The reaction o f N-trim ethylsilyl-N,N',N'-trim ethylethylenediam ine (1) with (Pr'0)2PCl furnished the acyclic, trimethylethylenediamine-substituted phosphorus(III) compound 4. There is no N M R spec troscopic evidence for an intramolecular donor-acceptor interaction between the phosphorus atom and the nitrogen atom o f the dim ethylam ino group in 4. The oxidation o f the trivalent phosphorus atom in 4 and in the related com pound 5 by sulfur, selenium, tetrachloro-o-benzoquinone, and hexafluoroacetone led to the corresponding A4P com pounds 6 -9 and to the A5P com pounds 10 and 11. N o intramolecular donor-acceptor interaction could be detected in any o f these products. There was no reaction between 5 and elemental tellurium. The reac tion products were characterized by N M R spectroscopy, mass spectrometry, and by elemental analysis. | | |

| The 7,8-Benzo-5-chloro-1,4,4-trimethyl-1 -aza-4-azonia-6,9-dioxa-5/l5-phosphaspiro[4. The 'H N M R spectrum o f the spirophosphorane 3 at room temperature indicates dynamic behaviour o f the cation. The low-temperature 'H N M R spectra o f 3 exhibit two sets o f dou blets for the protons o f the diastereotopic N (C H 3)2 groups. The free enthalpy o f activation for the dynamic process was determined (58.6 KJ/mole). In the reaction o f 3 with sodium tetra-phenylborate the crystalline com pound, 4, involving the non-coordinating anion, [B(C6H 5)4]~, was obtained. The X-ray crystal structure analysis o f 4 reveals the presence o f a five-membered ring, formally as a result o f intramolecular donor-acceptor interaction between the nitrogen atom o f the N (C H 3)2 group and phosphorus. The geometry at phosphorus deviates som ewhat from ideal trigonal bipyramidal. | | |

| Solvent Effects on the Carbon - 13 NMR Chemical Shifts and Rotational Barriers of N,N-Dimethylbenzamide - Solvent Enhanced n Polarization  | | | Abstract
| The 13 C NMR chemical shifts of N,N-dimethylbenzamide in thirty solvents have been measured at high dilution. The solvent induced chemical shifts (s.i.c.s.) of the carbonyl group carbon atom in twenty three solvents and the thermodynamic barriers to rotation about the C-N bond in eleven solvents are linearly related to the solvent parameter, ET(30). Multi-parametric analysis of the carbonyl s.i.c.s. indicates hydrogen bond donor effects are more important than polar effects. Rotational barriers for N,N-dimethylbenz-amide may be determined by measurement of the 13 C chemical shift of the carbonyl group in a particular solvent. The s.i.c.s. of the aromatic ring carbon atoms may be explained by the polarization of the aromatic ji electron system induced by the solvent enhanced polarization of the dimethylcarboxamido moiety. Hydrogen bonding solvents and polar solvents result in two effective dipoles on the dimethylcarboxamido moiety, which polarize the aromatic n electron system differently. | | |

| The N,N'-bis(trimethylsilyl)benzamidinato complexes [C 6 H 5 -C(NSiMe 3) 2 MCl 3 ] 2 (M = Ti. Zr) have been prepared by the reactions of N,N,N'-tris(trimethylsilyl)benzamidine, [C 6 H 5 — C(NSiMe 3)N(SiMe 3) 2 ] with titanium tetrachloride, and zirconium tetrachloride, respec-tively. The compounds form moisture sensitive, dark red (Ti) and white (Zr) crystals, which were characterized by crystal structure determinations. [C 6 H 5 —C(NSiMe 3) 2 TiCl 3 ] 2 : space group P2,/rc. Z = 2, 4373 observed independent reflexions, R = 0.034. Lattice dimensions (-90 °C): a — 959.0(8); b = 1196.5(8); c = 1770.9(11) pm; ß = 93.79(4)°. [C 6 H 5 -C(NSiMe 3) 2 ZrCl 3 ] 2 : space group P2,/«. Z = 2, 3160 observed independent reflexions, R = 0.031. Lattice dimensions (-90 °C): a = 971.6(7); b = 1222.2(9); c = 1792.9(10) pm; ß = 93.51(5)°. Both complexes crystallize isotypically, forming centrosymmetric dimeric molecules via chloro bridges with bond lengths of 242.0 and 253.8 pm (Ti), and of 253.7 and 264.9 pm (Zr). The metal atoms complete their distorted octahedral surroundings with two chlorine ligands and the nitrogen atoms of the chelating amidinato ligand. The N atoms of the amidinato group are in equatorial and axial positions. This accounts for the different metal-nitrogen bond lengths of 207 pm (ax) and 199 pm (eq) in the titanium compound and 219 pm (ax) and 214 pm (eq) in the zirconium complex. | | |

| Reaktivität nitrophenylsubstituierter cyclischer Amine bei Dehydrierungen The Reactivity of Nitrophenyl Substituted Cyclic Amines with Dehydrogenations  | | | Abstract
| Piperidine and perhydroazepine bearing a 1 -(4-nitrophenyl) substituent were inert to mercury-edta, while the a-pipecoline derivative gave an aminoketone with cleavage of the heterocycle. However the corresponding (2-nitrophenyl) compounds reacted to give respectively a piperidin-2-one, an aminopentanal and an aminohexanone. By an additional substituent in 2'-position the p-nitro compounds underwent dehydrogenation too. With a methyl group resulted a pattern analogous to o-nitro products. A neighbouring hydroxymethyl function enhanced the reaction with formation of benzoxazines and if possible their further oxidized derivatives, the hydroxylactams. | | |

| The applicability of ketals was examined for masking the carbonyl group in N-tertiary 4-piperidones during the dehydrogenation using mercury-edta. Various 1,3-dioxolanes showed a different behaviour in dependence on the N-substituent. With simple aliphatic moieties mainly dehydrogenated but hydrolyzed products were received. These enaminones were also available from the dehydrogenations of the corresponding 4-piperidones. Similar applied to para-acyl-aromatic substituted derivatives but with less yields. Aromatic substituents bearing a neighbour group on ortho-position with participation gave rise to different oxidation products partially with preservation of the ketal structure. | | |

| -phenylglycinemethylester reacts with Pd(OAc)2 in acetic acid to give the orthopalladated, acetato bridged complex 1. Treatment of 1 with sodium halide affords the chlo-ro, bromo, and iodo bridged compounds [Me2N C (H)(C 02Me)C6H4PdX]2 (2a -c) (X = halide). From 2a and 1,1 '-bis(diphenylphosphino)ferrocene the phosphine bridged trinuclear complex 3 is obtained. Substitution of the amine ligand of 2a by the phosphino group is observed for the reaction of 2a with Ph2PC(Me)C(Me)PPh2. Insertion of 2,6-dimethyl-phenylisocyanide, CO, alkyl-vinyl-ketones, and diphenylacetylene into the Pd-C bond o f 2a -c provides the ortho substituted organic and organometallic derivatives of phenylglycine 6a -c, 7, 8a -b and 9a -c. The crystal structures of 1, 4a, 6a, 7 and 9a were determined by X-ray diffraction. | | |

The novel sulfinamides R S (0) -N (S 0 2M e)2, where R = Me (la) or CC13 (lb), were ob tained by treating the corresponding sulfinyl chlorides with Me3S iN (S 02Me)2 or AgN-(S 0 2Me)2, respectively. A presumedly ionic 1:1 adduct of lb with 4-dimethylaminopyridine was isolated and analytically characterized. In the crystals of la (monoclinic, space group P2\!ri) and lb (monoclinic, P l j c) , the molecules feature approximately planar NS3 moieties, unusually long S (0) -N bonds and, in the case of lb, an extremely long S (0) -C bond [for la and lb, in order: sum of bond angles at nitrogen 359.5 and 357.1°, S (0) -N 178.2(2) and 173.6(2) pm, S (0) -C 178.8(2) and 194.1(2) pm]. In both molecular structures, an attractive S (0) --0 1,4-interaction leads to a 7.3° discrepancy in the S (0) -N -S 0 2 angles. The crystal packing of la displays a tape (double-chain) motif generated by two prominent intermolecu-lar C -H -O interactions involving one M e S 0 2 group and the sulfinyl oxygen atoms of two adjacent molecules, whereas in lb the molecules are associated into parallel chains via a bonding C l-"0(sulfonyl) interaction. | | |
