The chloro-bridged complexes [Cp*MCl2]2 (Cp* = C5Me5, M = Ir, Rh), [(p-cymene)RuCl2]2, [(C6Me6)RuCl2]2 and [(PEt3)PdCl2]2 react with SAMP by cleavage of the chloro bridges to give the corresponding monomeric h1-SAMP complexes. The x-ray structural detns. of [Cp*RhCl2NH2N(CH(CH2OCH3)(CH2)3)] I and [cyclic] [(C6Me6)RuCl2NH2N(CH(CH2OCH3)(CH2)3)] show coordination of the amino group in these complexes. From the chloro-bridged complexes, SAMP and sodium a-ketocarboxylates Schiff-base N,O-chelate complexes were obtained. The structure of the [Cp*(Cl)IrO2CC(CH3):NN(CH(CH2OCH3)(CH3)3)] complex with coordination of the carboxylate-O and the imine-N atom was detd. by x-ray diffraction. [on SciFinder (R)]
