چکیده
|
An organocatalytic protocol for the synthesis of dimethyl carbonate has been developed. under the catalysis of 5. mol% n-heterocyclic carbenes,ethylene carbonate undergoes transesterification reaction with methanol under very mild reaction conditions,producing dimethyl carbonate with high efficiency. furthermore,this n-heterocyclic carbene promoted transesterification can be scaled-up easily without lose of the conversion of dimethyl carbonate. © 2014.
