	Title	Reactive E=C (p-p)jr-Systems III [1]: Diels Alder Reactions with F 3 CP=CF 2 as Dienophile
	Abstract	The perfluorophosphaalkene F 3 CP=CF 2 (1) reacts as a dienophile at temperatures between —20 and +15 °C with cyclopentadiene, 1,3-cyclohexadiene, butadiene and 2,3-dimethyl-butadiene, respectively, giving the corresponding Diels-Alder adducts 2 to 5 in high yields. The observed reactivity proves the close relationship of P=C and C=C systems. CF2 >F^ CF 2

	Abstract	The phase-transfer-catalytically in situ generated dihalocarbenes CC1 2 and CBr 2 are inserted into a ß-C—H bond of the five-and six-membered phosphamanganacycloalkanes (OC) 4 MnPPh 2 (CH 2)"CH 2 CH 2 (la, b) [n = 1(a), 2(b)] to give the functionalized metallacycles (OC) 4 MnPPh 2 (CH 2)"CH(CHX 2)CH 2 (2a, a', b, b') [X = Cl: n = l(a), 2(b); X = Br: n = l(a'), 2(b')]. 2b crystallizes in the orthorhombic space group Pbca with Z = 8 and has a distorted chair conformation with equatorial position of the CHC1 2 group. The envelope conformation of 2a in solution was elucidated by means of 'H and 13 C{'H} NMR spectroscopic investigations.

	Title	NMR-spektroskopische Untersuchungen an Chalkogenverbindungen, VI [1] S-Isotopeneffekte auf 19 F-NMR-Frequenzen und ihre Abhängigkeit von Bindungslängen NMR Spectroscopic Studies on Chalcogen Compounds, VI [1] l4 S Isotope Effects on 19 F NMR Frequencies and their Dependence on Bond Lengths
	Abstract	Nineteen values for 34 S-induced isotope shifts on the NMR frequency of directly bonded fluorine of fourteen S(II), S(IV), and S(VI) compounds are reported. The dependence of these l A 19 F(34/32 S) values on the S —F bond length is demonstrated. Three reasons for this correlation are discussed. (1) A nonlinear dependence of nuclear shielding on bond distance. (2) Decreasing energy difference of two isotopomers with increasing bond distance. (3) Decreasing anharmonicity of the potential curve with increasing bond length. Some previously unknown S—F bond distances have been estimated by this correlation. The isotope shifts decrease with increasing temperature. This is attributed to vibrationally excited states in conjunction with a nonlinear dependence of nuclear shielding on bond distance. Furthermore, 34 S-induced isotope shifts on fluorine-19 over two bonds, 2 A 19 F(34/32 S), have been observed for the first time, and the 33 S-induced isotope effect in SF 6 has been measured.

	Abstract	(Me 3 P)2Ni(C 2 H4) (5) and (dmpe) 2 Ni2(C 2 H4)3 (6) react with various alkynes including ethyne (acetylene) and 1-alkynes to form the crystalline compounds (Me 3 P) 2 Ni(C 2 RR'), (dmpe)Ni(C 2 RR'), and (dmpe)2Ni 2 (C 2 R2) 2 (R.R' = H, Me, Ph). Structural assignments were made on the basis of : H, I3 C, and 31 P NMR data. The crystal and molecular structure of (dmpe)Ni(C 2 Ph 2) (17) has been determined by X-ray crystallography.

	Abstract	The coordination of tertiary phosphinothioform-amides and the isomeric S-alkyl phosphinothioform-imidates to BrRe(CO) 5 gives the /ac-bromotricar-bonylrhenium complexes la, b and 2a, b with P,S-chelate ligands. Unlike the analogous manganese complexes, the NMR spectra of dissolved lb and 2a, b show a splitting of the N-alkyl ('H, 13 C) and phosphorus signals indicating E/Z isomerisation of the ligands.

	Title	Preparation and Characterization of Some Isoelectronic Boron-Nitrogen Analogs of Substituted Uracil [1]
	Abstract	Several l,3,5-triaza-2-boracyclohexa-4,6-diones, which are isoelectronic analogs of substituted uracil, have been prepared by condensation reactions of boranes with biurets. They include species containing a NH or BH unit as potentially reactive sites. The latter are extremely sensitive to hydrolysis but are readily handled as the 2-methylaminoethanol derivative containing four-coordinate boron.
