资源简介:

Pincer ligand metalation is presumed to proceed via initial coordination to the phosphorus atoms followed by C–H oxidative addition. Few isolated intermediates in this process are known. A rhodium phosphinite complex has been isolated and structurally characterized that exhibits a strong agostic interaction with a C–H bond in the ligand backbone. The [(tBuPOCOP)­Rh­(CO)­H]+ system exhibits greater acidity and reactivity than the analogous iridium species (tBuPOCOP = κ3-C6H3-1,3-[OP­(tBu)2]2).
