摘要
Cyclopalladated phosphine free pyrazole complexes 1 and benzothiazole complexes 2 are excellent catalysts for the Heck vinylation of aryl iodides and termolecular queuing cascades, leading to turnover numbers of > 10(6) in some cases, at moderate temperatures; these catalysts show high thermal stability and are not sensitive to moisture and air.
