Facile oxidative addition of water at iridium: reactivity of trans-[Ir(4-C5NF4)(H)(OH)(PiPr3)2] towards CO2 and NH3

Abstract

A reaction of trans-[Ir(4-C5NF4)(η2-C2H4)(PiPr3)2] (1) with an excess of water in THF at room temperature affords the hydrido hydroxo complex trans-[Ir(4-C5NF4)(H)(OH)(PiPr3)2] (2). Treatment of 2 with CO furnishes trans-[Ir(4-C5NF4)(H)(OH)(CO)(PiPr3)2] (3). Reductive elimination of water from 3 leads to the formation of the iridium(I) carbonyl complex trans-[Ir(4-C5NF4)(CO)(PiPr3)2] (4). The insertion of CO2 into the Ir–O bond of 2 forms the hydrido hydrogencarbonato complex trans-[Ir(4-C5NF4)(H)(κ2-(O,O)-O2COH)(PiPr3)2] (5). Treatment of 2 with NH3 in C6D6 yields trans-[Ir(4-C5NF4)(H)(OH)(NH3)(PiPr3)2] (6). Storage of the reaction mixture at room temperature reveals the formation of the N–H activation product [Ir(4-C5NF4)(H)(μ-NH2)(NH3)(PiPr3)]2 (7).
