Applicazioni

Ionic liquids can effectively accelerate slow N-benzylation reactions utilizing dibenzyl carbonate as an alkylating reagent. Dibenzyl carbonate (DBzlC) has been used to benzylate phenylacetonitrile, benzyl phenylacetate and phenol. Selective N, N-dibenzylation of primary aliphatic amines was carried with dibenzyl carbonate in the presence of phosphonium salts.

Note

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents, heat.

Benzylating agent, e.g. in preparation of benzyl ethers of thiols with K2CO3/ 18-crown-6: Synthesis, 382 (1986). Benzylation of phenols and monobenzylation of active methylene compounds have been accomplished using K2CO3 in DMF: J. Chem. Soc., Perkin 1, 1889 (1995).
