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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
