Abstract

Hail boration! 2‐Dimethylaminopyridine‐ligated dihaloborocations [X2B(2‐DMAP)]+ with a strained four‐membered boracycle were used for the haloboration of terminal and dialkyl internal alkynes (see scheme). Esterification then provided vinyl boronate esters as useful precursors to tetrasubstituted alkenes. Following mechanistic studies, the scope of the haloboration was expanded simply by variation of the amine. Pin=2,3‐dimethyl‐2,3‐butanedioxy. [ABSTRACT FROM AUTHOR]
