PREPARATION OF SEVERAL NEW TRANSITION METAL HYDRIDO COMPLEXES OF A TYPE MH(Y)Ln (M = Ni, Pd, Pt; Y = IMIDO, ALKENYL CARBOXYLATO) AND ELIMINATION OF HY FROM THE COMPLEXES ON INTERACTION WITH π-ACIDS

MH(succinimido) (PCy3)2 (M = Ni, Pd) and trans-PtH(OCOR) (PCy3)2(R = –C(CH3)=CH2, –CH2CH=CH2) have been prepared by oxidative addition of succinimide or the corresponding acid to the zero-valent transition metal complexes. Treatment of the hydrido complexes with π-acids such as CO and maleic anhydride causes elimination of succinimide or RCOOH.
