摘要：
[Ir(cod)(β-dik)] complexes (β-dik=2,4-pentanedionato or 1,1,1-trifluoro-2,4-pentanedionato ligands; cod=cycloocta-1,5-diene) react with CH3I in acetone to form Ir(III) alkyl compounds. The addition of Br- led to the formation of a five-coordinate intermediate which enhanced the reaction rate of the acac complex and gave the same oxidative addition product compared to the uncatalysed reaction. A reaction mechanism is given. © 1990.
