Borylcyanocuprate in a One‐Pot Carboboration by a Sequential Reaction with an Electron‐Deficient Alkyne and an Organic Carbon Electrophile

Open publisher page 123 citations

Abstract

A key reactive species, lithium borylcyanocuprate, was isolated and fully characterized in a one-pot carboboration of alkynes. The carboboration involves a boryllithium, CuCN⋅2 LiCl, an ester-substituted alkyne, and an organic electrophile (see scheme). By changing the reaction temperature, the syn/anti ratio of the carboborated products can also be changed.
