Preparation and reactivity of 16-electron ‘half-sandwich’ ruthenium complexes; X-ray crystal structure of (η⁵-C₅Me₅)Ru(PPrⁱ₃)Cl

Abstract

The new 16-electron ruthenium compounds (η5-C5Me5)Ru(L)Cl [(1), L = PPri3; (2), L = PCy3](Cy = cyclohexyl) were prepared from [(η5-C5Me5)RuCl]4 and PPri3 or PCy3, respectively, and the X-ray crystal structure of (1) has been determined; reactions of the title compounds with CO, C2H4, pyridine, and PhSiH3 are described.
