Abstract

Abstract New styryl ruthenium-molybdenum and -tungsten complexes Cp(CO)3M-Ru (trans-styryl)(CO)(PPh3)2 [M = Mo (2), W (3)] have been prepared by the metathetical reactions of Ru(trans-styryl)Cl(CO)(PPh3)2 with Na[MCp(CO)3]. The reactions of 2 with CO and with PMe3 give Cp(CO)3Mo-Ru(trans-styryl)(CO)2(PPh3)2 (4) and Cp(CO)3Mo-Ru(trans-styryl)(CO)(PMe3)2 (5), respectively. The complexes of 2, 3, 4, and 5 have been characterized by IR, 1H NMR, 31P{1H} NMR spectroscopy, and elemental analysis.
