An evaluation of palladium-based catalysts for the base-free borylation of alkenyl carboxylates

Abstract

Synthesis of organoboron derivatives is a key application of catalytic cross-coupling, with the Pd-catalyzed Miyaura borylation among the most versatile methods available. We have evaluated several Pd-based systems for borylation of alkenyl acetates and pivalates, with the optimal system heavily dependant on the substrate structure.
