Article abstract of DOI:10.1007/BF02251636

Reactions of C- and N-nucleophiles at the carbonyl group of 8,11,11-trimethyl-11-silabenzo-[b]naphtho[2,3-d]thiophen-6-one have been studied. PMR Spectroscopy showed that condensation with aniline gives a mixture of the Z- and E- isomers of the corresponding azomethine. Reaction with n-butyl and phenyllithium gave tertiary alcohols, the molecular structure of which was proved using X-ray crystallography. 1999 KluwerAcademic/Plenum Publishers.
