A selective reaction of the" ate" complexes formed with 1-alkenylboronic esters and organolithium or Grignard reagents, by treatment with either Bronsted or Lewis acids at-78" C to give the corresponding organylalkenylborinic esters, is explored in this study. This systematic, detailed study reveals that the nature of the alkoxy group on boron, the nature and the amount of the alkyllithium or Grignard reagent used, the solvent, the reaction ...
