应用

Deoxazole-quat is an N-heterocyclic carbene salt which activates tertiary free alcohols for a C-C cross coupling reaction with aryl halides. The MacMillan group developed a mild, robust, and selective metallaphotoredox-based cross-coupling platform for the deoxygenative coupling for free alcohols using Deoxazole-quat, a Ni catalyst, and [Ir(dtbbpy)(ppy)2]PF6.

Metal-catalysed cross-couplings are a mainstay of organic synthesis and are widely used for the formation of C-C bonds, particularly in the production of unsaturated scaffolds1. However, alkyl cross-couplings using native sp3-hybridized functional groups such as alcohols remain relatively underdeveloped2. In particular
