DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The 13C NMR spectra of 39 alkoxysilanes RnSi(OR1)4-n (R = H, Ph, Me, R1 = alkyl, Ph) were recorded and assigned. The chem. 1825-58-7 and 1825-59-8 which are cas registry numbers of chemicals are mentioned. shifts of the .alpha.-C resonances of the alkoxy group were dependent on the nature of R1 and the nature and no. of the other Si substituents. Regression analyses of the data give empirical substituent chem. shift parameters for the Si substituents. The .beta.-C resonances are dependent on the presence of Si but not on its specific substituents. .
