processes for the preparation of iridium complexes carbonyl and new products obtained, used as carbonylation catalysts

摘要

The complexes [Ir(CO)3I], [HIr(CO)3I2], [HIr(CO)2I2(H2O)], [RIr(CO)2I2], [(RCO)Ir(CO)2I2] where R is an alkyl radical, are described. Processes for preparing the aforesaid complexes are described and in addition a new process for preparation of [Ir(CO)3I3] is described.
