Reactions of Cp*Ir(CO)2 with pentafluorobenzonitrile : half-sandwich iridium complexes Cp*Ir(CO)(p-C6F4CN)(X)

Reactions of Cp*Ir(CO)2 with pentafluorobenzonitrile : half-sandwich iridium complexes Cp*Ir(CO)(p-C6F4CN)(X)

The reaction of Cp*Ir(CO)2 (1) with pentafluorobenzontrile in the presence of a base afforded the diaryl complex Cp*Ir(CO)(p-C6F4CN)2 (4). The reaction proceeds via the metallacarboxylic acid Cp*Ir(CO)(p-C6F4CN)(COOH) (2). The latter can be decarboxylated in the presence of a base to the hydrido spe...
