Abstract

Carbon–carbon (sp2–sp2 and sp1–sp2) and carbon–nitrogen (nucleophilic allylation) coupling processes are promoted by a catalytic system containing [PdCl (η3–C3H5)] 2 with the new ferrocenyl bis (difurylphosphine) 1, 1′-bis [di (5-methyl-2-furyl) phosphino] ferrocene, Fc [P (FuMe) 2] 2. Starting from aryl bromides or allylic acetates this versatile catalyst system may be used at low palladium loadings (10− 1–10− 4mol%) in some Heck, ...
