| Abstract: | A dichloromethane solution of the cationic carbonyl complex IrCl2(CO)(PMe2Ph)3)]ClO4] reacts with aqueous KOH to give IrCl2(CO2H)(PMe2Ph)3] which has been characterised spectroscopically. This CO2H compound is very much more basic and very much less acidic than IrCl2(CO2H)(CO)(PMe2Ph)2). Tertiary amines will not deprotonate IrCl2(CO2H)(PMe2Ph)3] while LiN(SiMe3)2] leads to decarboxylation products trans, mer- and cis, mer-IrHCl2(PMe2Ph)3]. The mechanisms of these reactions are considered and the hydroxycarbonyl complex is compared with its formato isomer which decarboxylates much less readily. |
