Abstract
Derivatives of the type (C~6~H~5~)~3~MβOH, where M ο£Ύ C, Si and Ge, were condensed with N,Nβdiethylaminoβtrimethylsilane in xylene solvent at 50Β°. The rates of the condensation reaction for this series (C, Si,Ge) were found to be in the ratio of approximately 1 : 3 : 1, respectively.

The cyeloadduct 1 exists in a mobile equilibrium with isoquinolinium N-phenylimide (2) and CS 2. The reaction of 1 with 1-(diethylamino)propyne (3) afforded the 1:1:1 products 4 and $, the latter predominating with higher CS 2 concentration. The NMR spectra and an X-ray analysis of 4 clarified the s
## Abstract Siliconβ29, carbonβ13 and oxygenβ17 NMR data are reported for the methylethoxysilanes, Me~__n__~Si(OEt)~4β__n__~ with __n__ = C to 3. The values of ^1^__J__(SiC) vary greatly, in a manner which appears to be inconsistent with an effect of __s__βcharacter variation alone. The chemical sh
