Reaction of trifluoroacetonitrile with π-allylic-iridium complexes; the crystal structure of an iridium(I) six-membered ring chelate complex
Abstract
[Ir(π-2-Me-C3H4)(CO)(PPh3)2] reacts with CF3CN to afford an iridium(I) six-membered chelated complex, identified by X-ray crystallography; whereas, with [Ir(π-1-MeC3H4)(CO)(PPh3)2] C4H6 is displaced and a five-membered ring system is formed from two CF3CN molecules joined head to tail.
