Abstract

Abstract The aminophosphine-based pincer complexes [C 6 H 3-2, 6-{XP (piperidinyl) 2} 2 Pd (Cl)](X= NH 1; X= O 2) are readily prepared from cheap starting materials by sequential addition of 1, 1′, 1′′-phosphinetriyltripiperidine and 1, 3-diaminobenzene or resorcinol to solutions of [Pd (cod)(Cl) 2](cod= cyclooctadiene) in toluene under N 2 in “one pot”. Compounds 1 and 2 proved to be excellent Heck catalysts and allow the quantitative ...
