Novel reactivity and low temperature (–60 °C)X-ray crystal structure determination of Ru(CO)2(η2-SO2·SO2)(PPh3)2
Abstract
Crystals of the title complex have been obtained from SO2 saturated benzene–heptane solutions of Ru(CO)3(PPh3)2, and an X-ray crystal structure determination at –60 °C has shown not only η2-SO2 co-ordination to the ruthenium, but also a second molecule of SO2 co-ordinated to the terminal oxygen of the η2-SO2; reaction with excess of SO2 and PPh3 under anaerobic conditions results in stoicheiometric production of Ru(SO4)(CO)2(PPh3)2 plus PPh3S.
