Synthesis, structural characterization, and activity on the transfer hydrogenation reaction of dimesitylacetonate piano stool organometallic complexes of Ru(II), Rh(III), and Ir(III)

摘要

A new small family of Ru, Rh, and Ir piano-stool complexes partially containing the bulky acac(diMes), p-Cymene and Cp* ligands was synthetized and characterized. Their catalytic activity in transfer hydrogenation reaction was tested. The turn over frequency (TOF) values for aromatic- and alkyl-ketones giving the corresponding desired alcohols were increased in two orders of magnitude by using microwave heating compared with conventional thermal method.
