DOCUMENT TYPE: Journal CA Section: 21 (General Organic Chemistry) The combination of a bulky aliph. phosphine, e.g. tricyclohexylphosphine or the tetrafluoroborate salt of tri-tert-butylphosphine, with the Pd(0) complex of a 15-membered triolefinic macrocycle is an excellent catalyst for the Suzuki cross-coupling of aryl and heteroaryl bromides and chlorides. The palladium can be recovered in the form of the initial complex. .
