摘要:
An orthopalladated complex of commercially available tris(2,4-di-tert-butylphenyl)phosphite proves to be an extremely active catalyst in the Heck arylation 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)).
