Organoborierung von Alkinylstannanen, VIII [1] Zur Reaktion von Alkinyltrimethylstannanen mit 1-Boracyclopentanen und Methylbis(tert-butyl)boran / Organoboration of Alkynylstannanes, VIII [1] The Reaction of Alkynyltrimethylstannanes with 1-Boracyclopentanes and Methy Ibis (tert-butyl) borane

Schmidt, Axel | Wrackmeyer, Bernd
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.
