Selective mono-benzylation of methylene active compounds with dibenzyl carbonate: benzylation of phenol [PDF]

open access: yesJournal of the Chemical Society, Perkin Transactions 1, 1995
Dibenzyl carbonate (DBzlC) has been used to benzylate phenylacetonitrile, benzyl phenylacetate and phenol. In refluxing N,N-dimethylformamide (DMF) as solvent, and in the presence of K2CO3 phenol yielded benzyl phenyl ether and phenylacetonitrile the monobenzylated compound 2,3-diphenylpropionitrile.
