Abstract
A new tertiary phosphine containing α,β-unsaturated β-amino ketone, 4-[2-(diphenylphosphino)ethylamino]-3-penten-2-one (Hdpeap), reacts with sodium tetrachloropalladate(II) in the absence or presence of sodium ethoxide to give [PdCl2(Hdpeap)2] or [PdCl(dpeap)] [dpeap ≡ 4-[2-(diphenylphosphino)ethylamino]-3-penten-2-onatoO,N,P], respectively. The latter complex reacts with terminal acetylenes in the presence of catalytic amounts of copper(I) iodide to produce alkynyl complexes, [Pd(C≡CR)(dpeap)]. Carbanions derived from active methylene compounds, and sodium dimethyldithiocarbamate also react with [PdCl(dpeap)] to afford [Pd(CHYY′)(dpeap)] and [Pd(S2CNMe2)2], respectively.
