一般描述
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.
应用
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.
