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.
已经开发出通过使用弱碱进行的1,2-二醇的催化单烷基化。二氯化铜(II)和硼酸是在碳酸钾作为碱存在下活化1,2-二醇的有效催化剂。通过为每种1,2-二醇选择合适的催化剂,将各种1,2-二醇与烯丙基,苄基和烷基卤化物在DMF中选择性地单烷基化。
