摘要

By using a nickel complex with an N-phosphinomethyl- N-heterocyclic carbene ligand (NHC-P), the reducing ability and thermal stability of the complex were improved considerably compared to the previously reported bipyridine and bisphosphine complexes, and acrylate salt was prepared from ethylene and CO_2 with the highest TON ever reported for nickel systems even without using metallic zinc. Oxidative cyclization of ethylene and CO_2 on the NHC-P nickel complex was found to proceed very rapidly compared to previous systems.
