9 Decarbonylative/Decarboxylative Borylation

Abstract

Organoboron species are versatile building blocks and have been widely used in the synthesis of bioactive molecules, natural products, and organic materials. Accordingly, approaches to access such compounds have been widely explored. Carboxylic acids, which are ubiquitous and abundant organic feedstocks, can be transformed into their borylated counterparts via several different catalytic or stoichiometric approaches. In this review, decarboxylative borylation reactions, which form a carbon–boron bond with elimination of carbon dioxide, are detailed in terms of reaction conditions, substrate scope, and experimental procedures.

Key words

decarboxylative borylation - decarbonylative borylation - decarboxylation - borylation - carboxylic acids - boronic acids - boronic acid esters - boronates - light-induced reaction - photoredox catalysis - nickel catalysis - copper catalysis - redox-activated esters - N-hydroxyphthalimides
