NMR Studies on Silylphosphines. II. Effects of Substituents in Silyl- and SilylmethylphosphinesThe influence of the substituents [CH3, H, H3Si, (CH3)3Si] on: chemical shifts of protons and phosphorus nuclei: the 29Si-31P coupling constant; and several proton coupling constants in the nmr spectra of 24 silylphosphines of the series (CH3)xH3-x,Si-PH2, (CH3)xH3-xSi-PHCH3, (CH3)xH3-xSi-P(CH3)2, [(CH3)xH3-xSi]2PH, [(CH3)xH3-xSi]2PCH3, [(CH3)xH3-x,Si]3P has been studied. Empirical methods for the calculation of δ31P and J29Si-31P using bond increments are reported.
Notes:
Es wird der Einfluß der Substituenten [CH3, H, H3Si, (CH3)3Si] auf die chemische Verschiebung der Protonen und der Phosphorkerne sowie auf die 29Si-31P-Kopplungskonstante und auf einige Protonenkopplungen in 24 Silylphosphinen der Gruppen (CH3)xH3-x,Si-PH2, (CH3)xH3-xSi-PHCH3, (CH3)xH3-xSi-P(CH3)2, [(CH3)xH3-xSi]2PH, [(CH3)xH3-xSi]2PCH3, [(CH3)xH3-x,Si]3P anhand der NMR-Spektren untersucht. Es werden empirische Verfahren zur Berechnung von δ31 und J29Si-31P aus Bindungsinkrementen mitgeteilt.
