A systematic study on copper(II) as catalyst for the synthesis of glycerol carbonate via oxidative car-bonylation is here reported for the first time. Copper(II) chloride has been found to efficiently promotethe process under homogeneous conditions treating glycerol with CO:O2(Ptot= 4 MPa; P(O2)= 0.7 MPa),in DMA at 130◦C and in the presence of pyridine as co-catalyst. Excellent conversions (>92%) and selec-tivities (>93%) are obtained in relatively short reaction times (3–4 h) also with copper(II) complexes.The catalyst overall TON is evaluated and new experimental evidences are provided allowing significantadvancements in the mechanism comprehension.
