A Novel Synthesis of Halogenated gem-Diboron Reagents

Abstract

A novel synthesis of halogenated gem-diboronates (X-CR(Bpin)2) was developed. The reagents are stable and easy to prepare in a large scale. Tetra-substituted halogenated gem-diboronates can be prepared in high yields when using alkyl-substituted gem-dihalides, providing a new strategy for the synthesis of new gem-diboron compounds.
