Facile oxidative amination with imidazole and L-histidine coordinated cobaloximes

Abstract

The simple, robust, and synthetically adaptable cobaloxime core provides an ideal catalytic model for photo- and electrocatalytic H2 production. Water solubility, oxygen tolerance, and acid stability make these catalysts appealing for sustainable chemistry applications. In this study, we explored cobaloximes with axial imidazole or L-histidine coordination [Co−DMG−X; imidazole, histidine] in photocatalytic hydrogen atom transfer (HAT) reactions for the synthesis of N-aryl azoles from arenes and azoles.
