Addition of phosphine ligands can produce high yields of tetraphenoxymethane, TPM, and diphenylcarbonate, DPC, in short reaction times and improved reaction rates by a copper-induced condensation of phenol and carbon disulfide, CS2. Either aromatic or aliphatic substituted phosphine ligands can be e...
