产品介绍

Dibenzyl carbonate (DBC) is commonly used as a benzylating agent. Dimethyl carbonate and excess of benzyl alcohol undergoes transesterification in the presence of CsF/α-Al2O3 (cesium fluoride/aluminum oxide) to form DBC. The formation of N,N-dibenzyl derivatives by the reaction of primary aliphatic amines with DBC in the presence of phosphonium salts has been investigated;
Dibenzyl carbonate may be used in the synthesis of the following via benzylation reaction:
• Benzyl phenyl ether from phenol. 
• 2,3-Diphenylpropionitrile from phenylacetonitrile. 
• Benzyl 2,3-diphenylpropionate from benzyl phenyl acetate
