A13C, 17O, 19Si NMR study of some silicon, germanium and tin acyloxyderivatives
摘要:
C-13, O-17, Si-29, Sn-119 NMR spectra of acyloxysilanes, -germanes and -stannanes R1R2R3MOCOR (M = Si, Ge, Sn) have been investigated. The character of substituent effects on the C-13 and O-17 chemical shifts of these compounds is almost the same for Si, Ge and Sn. O-17 and Sn-119 NMR spectra establish the predominance of the intermolecular exchange processes in acyloxystannanes.
