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