A metallacyclic λ5-phosphaalkenyl complex of ruthenium(II): X-ray structure of [Ru{κ2-P(
O)CButC(
O)}(CNBut)2(PPh3)2]
Abstract
The reaction of [Ru(PCHBut)Cl(CO)(PPh3)2] 1 or [Ru(P
CHBut)Cl(CNBut)(CO)(PPh3)2] 2b with excess pivalo isonitrile under aerobic conditions provides the novel metallacyclic λ5-phosphaalkenyl-P complex [Ru{κ2-P(
O)CButC(
O)}(CNBut)2(PPh3)2], which has been crystallographically characterised.
