Abstract
The methylpalladium(II) methoxide complexes [Pd(Me)(OMe)(N~N)] (N~N)=tmeda or bpy) have been synthesized by alkoxidemethanol exchange of [Pd(Me)(OCH)(CF3)2)(N~N)] in MeOH. The bpy complex undergoes insertion of CO to give either a methyl(methoxycarbonyl) complex [Pd(Me)(CO2Me)(bpy)] (at −60°C) or an acyl(methoxycarbonyl) complex [Pd(COMe)(CO2Me)(bpy)] (at −25°C). Both carbonylated species were isolated and characterized at low temperature.
