Anwendungen

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.

Bemerkungen

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