资源简介：
The synthesis of two members of a new PCP pincer ligand family and their complexation with iridium has been developed. Double C–H activation results in a ligand anchored by a carbene donor; hydrogen reversibly adds to the (PCcarbeneP)IrCl complexes 3R (R = iPr, tBu). Aryl, amido, and phenoxy derivatives are available from the chlorides via salt metathesis. These compounds add H2 and eliminate H–X; the iridium compound is trapped as a PCalkylP iridium polyhydride.
