Conformational preferences of Si–Ph,H and Si–Ph,Me silacyclohexanes and 1,3-thiasilacyclohexanes. Additivity of conformational energies in 1,1-disubstituted heterocyclohexanes
Abstract The conformational equilibria of 1-phenyl-1-silacyclohexane 1, 3-phenyl-1,3-thiasilacyclohexane 2, 1-methyl-1-phenyl-1-silacyclohexane 3, and 3-methyl-3-phenyl-1,3-thiasilacyclohexane 4 have… Expand
Silacyclohexanes and silaheterocyclohexanes—why are they so different from other heterocyclohexanes?
Stereochemical studies on silaheterocyclohexanes is a ‘hot topic’ as evidenced by the growing number of publications. During last 10 years a substantial number of substituted silacyclohexanes and… Expand
The Carbon?Nitrogen Triad Prototropic Tautomerism
Data on the imine–enamine and related types of tautomerism are surveyed and different approaches to problems of the tautomerism of enamides, which play a major role in biological processes, are… Expand
Conformational analysis of 3‐methyl‐3‐silathiane and 3‐fluoro‐3‐methyl‐3‐silathiane
The conformational equilibria of 3-methyl-3-silathiane 5, 3-fluoro-3-methyl-3-silathiane 6 and 1-fluoro-1-methyl-1- silacyclohexane 7 have been studied using low temperature C-13 NMR spectroscopy and… Expand
