Abstract
1-Organyl-1-boracyclopentanes react with alkynyltrimethylstannanes to give 1-bora-cyclohexylid(2)enes as the only products. The analogous reaction with methylbis (tert-butyl)borane leads to a nonstatistical distribution of organoboration products. Structure and stereochemistry of the new compounds are discussed on the basis of methanolysis reactions and 1H, 11B and 13C NMR data.Keywords
