Aryl–Pd covalently bonded palladacycles, novel amino and oxime catalysts {di-μ-chlorobis(benzaldehydeoxime-6-C,N)dipalladium(II), di-μ-chlorobis(dimethylbenzylamine-6-C,N)dipalladium(II)} for the Heck reaction

Amine and oxime palladacycles with an aryl–Pd covalent bond were found to be robust catalysts for the Heck reaction of aryl iodides, bromides and even chlorides. High TONs and TOFs were obtained with these palladacycles.
