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 ?-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 zerovalent transition metal complexes.Treatment of the hydrido complexes with ?-acids such as CO and maleic anhydride causes elimination of succinimide or RCOOH.
