A palladium Chugaev carbene complex as a modular, air-stable catalyst for Suzuki–Miyaura cross-coupling reactions

A new Chugaev-type palladium carbene complex was prepared via a convenient metal-templated route and fully characterized by X-ray crystallography, NMR, and IR. This complex proved effective as a precatalyst for Suzuki–Miyaura cross-coupling reactions of a range of aryl bromides, even under aerobic conditions, and its modular synthesis should allow for further catalyst fine-tuning.
