Abstract
An orthopalladated complex of commercially available tris(2,4-di-tert-butyl phenyl)phosphite proves to be an extremely active catalyst in the Heck aryl ation of alkenes, with turnover numbers of up to 5,750,000 (mol product.mol Pd-1) and turnover frequencies of up to nearly 300,000 (mol product.mol Pd -1.h(-1)).
