摘要

Hydroboration of 1-alkylthio-1-alkynes with dicyclohexylborane or bis (1, 2-dimethylpropyl) borane proceeded smoothly, adding most of the dialkylboryl group to the α-position of the triple bond. The resulting alkenylboranes afforded either S-alkyl alkanethioates on a controlled oxidation with alkaline hydrogen peroxide in the presence of N, N, N′, N′- etramethylethylenediamine or (Z)-1-alkylthio-1-alkenes on a basic protonolysis, ...
