摘要

A catalytic monoalkylation of 1, 2-diols by using a weak base has been developed. Copper (II) dichloride and boronic acids are effective catalysts for activating 1, 2-diols in the presence of potassium carbonate as a base. Various 1, 2-diols were selectively monoalkylated with allyl-, benzyl-and alkyl-halides in DMF by choosing a suitable catalyst for each 1, 2-diols.
