 Title    Der Einfluß der Kettenlänge auf die massenspektrometrigche Fragmentierung höherer l.co-Diphenylalkane The Influence of the Chain Length on the Mass Spectrometric Fragmentation of Higher 1, co-Diphenylalkanes  
 Abstract    The mass spectrometric fragmentation of l,co-diphenylalkanes (2 < co < 22) has been studied in order to elucidate the effect of the chain length on the reactions of unstable and metastable molecular ions with respect to the occurrence of internally solvated ions in the gas phase. The unstable molecular ions of all l,co-diphenylalkanes react predominantly by formation of C?H7+ and C7Hg + " ions, the latter ones are also formed by metastable molecular ions. Neither the variation of the relative abundances of these fragment ions with the chain length nor the fragmentation of specifically deuterated molecular ions indicate any internal solvation in the reacting ions. Inspite of the localized activated C-H bonds at the benzylic positions, these "activated" H atoms are not involved in intra-molecular hydrogen exchange reactions or the formation of C7Hs + ' ions (with the exception of co = 3). Especially the higher homologues (co > 12) react very similarly to the molecular ions of 1-phenylalkanes, while the fragmentation of the lower homologues (co < 6) is determined by specific ("vinculoselective") competitive reactions, e.g. loss of CvH?' and CsHs.

 Title    Beiträge zur Chemie des Bors, 190 [1] Synthese und Molekülstruktur von 1,2-Dihydroboreten und Azadiboretidinen Contribution to the Chemistry of Boron, 190 [1] Synthesis and Molecular Structure of 1,2-Dihydrodiboretes and Azadiboretidines  
 Abstract    [2+2]-Cycloadditions of 9-Fluorenylidentetramethylpiperidinoboranes have been studied with selected olefines, acetylenes and iminoboranes. No reactions with olefines were observed. While propiolic methylester reacts exclusively at the carbonyl bond producing the oxaboretane 5, alkines such as diethylamino-alkines, cyclo-octine and phenylacetylene provide access to the'1,2-dihy-droboretenes 6, 3 and 2. Tetramethylpiperidinoiminoboranes make 1.2.4-azadiboretidines 7 available. 6a and 7a contain a folded four-membered ring as shown by X-ray structure analysis. There is only a weak 1,3-intraannular interaction due to BN-;r-bonding of the boron atoms with their exocyclic amino group.

 Title    A Novel Isomerization of an Electron-Rich Alkene  
 Abstract    Displacement of 2-methvlpropene from [Fp(Me2C = CH2)]BF4 (Fp = (/?5-C5H5)Fe(CO)2) by Z-1,2-dimethoxyethylene (Z-DME) gives [Fp(Z-DME)]BF4. Displacement by E-1,2-dimethoxyethylene (E-DME), in contrast, does not give the expected complex of E-DME, but rather the complex of the Z-alkene. A mechanism involving scission of the C = C bond of the coordinated alkene to give a bis-carbene intermediate is proposed.

 Title    Synthese eines Doppel-Carbodiphosphorans und seiner Vorstufen Synthesis of a Double-Carbodiphosphorane and its Precursors  
 Abstract    The reaction of 1,4-dibromobutane with bis(diphenylphospliino)methane (1) yields two products, one of which is identified as butane-l,4-bis[diphenyl(diphenylphosphinomethyl)-phosphonium bromide] (3 a). Transylidation of this bis-phosphonium salt using two equiv-alents of (CH3)3P = CH2 affords the bis-ylide [CH2CH2P(C6H5)2 = CH-P(C6H5)2]2 (4) in high yields. This conversion can be reversed on treatment of 4 with etheral HCl (to give 3b). Methylation of 4 with CH3I occurs at phosphorus, however, and produces the bis-semiylide salt (5), [CH2CH2P(C6H5)2CHP(C6H5)2CH3]2 2e 2Iö. Transylidation of 5 (again with (CH3)3P = CH2) leads to the bis-carbodiphosphorane (6), [CH2CH2P(C6H5)2 = C = P(C6H5)2CH3]2. All compounds were characterized by elemental and detailed NMR analyses. The second product of the above quaternisation reaction is a cyclic bis-phosphonium salt (2) with a seven-membered ring structure.

 Title    Syntheses of Anomeric Pairs of New C-Nucleosides via 1,3-Dipolar Cycloaddition Reaction, Part I  
 Abstract    A convenient pathway to a variety of ß-and a-C-nucleosides has been developed by utiliz­ ing 1,3-dipolar cycloaddition reactions of various exocyclic and endocyclic heterocyclic ylides with ß (5a) and a (5b) anomers of ethyl 3-(2',3'-0-isopropylidene-5'-0-trityl-D-ribofurano-syl) propiolate, respectively. Assignment of configuration at exposition of the C-nucleosides could be made by a comparative study of the properties of corresponding a and ß anomers with a reasonable degree of certainity.

 Title    New Diazasilaphosphetidines and their Precursors  
 Abstract    A series of aminosilanes (R 'H N bSiR : have been prepared. In case of bulky substituents R' the aminolysis of Ph^SiCb stops at the (R'HN)ClSiPh2 stage. Replacement of the Cl atom is achieved with LiNHR' which allows the synthesis o f mixed bisaminosilanes (R'HN)(R"HN)SiPh2. The X-ray structures of three of these compounds have been determined. There are no intermolecular N-H -N hydrogen bonds in these compounds in the solid state. Several 1,3,2,4-diazaphosphetidines have been synthesized using bis(N-lithioamino)silanes and bis(N-lithioamino)phosphanes . Amongst these the heterocycle 18 possesses an almost planar four membered N iSiP ring system.

 Title    Die Kondensation von Ylidylchlorphosphanen mit Phosphanen und Bis(diphenylphosphanyl)methan und -amin The Condensation o f Ylidyl Chlorophosphines with Phosphines and Bis(diphenylphosphino)methane and -amine  
 Abstract    Ylidyl chlorophosphanes 1 and dichlorophosphanes 2 react with trimethylsilyl phosphanes to yield the ylidyl diphosphanes 3, 4,5, 7 and the 2-ylidyl triphosphanes 8. From the reaction of compounds 1 with lithium diphosphanyl amide and diphosphanyl methanide result the ylidyl diphosphonium ylides 11 and ylidyl diphosphinimines 13. The former rearrange to give the ylidyl triphosphanyl methanes 12. The chloromethyl diphosphinimine 13c enters a cyclization to give the 1,2,3,5-azatriphosphole derivative 14, the structure of which has been solved by X-ray analysis. From the reaction of ylidyl bis(chlorophosphanes) 17 and 20 with the same reagents the 1,2,4,5-tetraphosphinine derivative 18 and the 1,2,3,5,6-azatetraphosphinine derivatives 19 and 21 are obtained.

The X-Ray Crystal Structures of [M(C5H4'Bu)2]PF6 (M = Fe, Co) and [ C o ^ H / B u ^ C o C ^ The hexafluorophosphate salts [Fe(C5H4'Bu)2]PF6 (1) and [C o ^H /B u ^lP F ö (2) crystal­ lize in isotypic structures with centrosymmetric cations which have a staggered (transoid) conformation of the exactly parallel ring ligands (conformational angle r = 180°).
