Activation of ethylene and ammonia at iridium: C–H versus N–H oxidative addition†
Abstract
The CH(CO2Me)}(NH3)2(PiPr3)] (5) are generated on reaction of cis-trans-[Ir(4-C5NF4)(H)2(PiPr3)2] (1) or of the
CH(CO2Me)}(PiPr3)2] (4) with NH3, respectively. Photolysis of 5 gives complex [Ir(4-C5NF4)(H){κ2-(C,O)-(Z)-(MeO2C)C
CH(COOMe)}(NH3)(PiPr3)] (6). Treatment of the
