developed with special attention focussed on the applicability of the reaction. Sodium alkoxide is used as the nucleophile, and the corresponding alcohol as the solvent. The reaction requires neither precious metals nor organic ligands. It uses a catalytic system consisting of copper(I) bromide as a catalyst, the corresponding alkyl formate as a noncontaminating cocatalyst, and lithium chloride as an additive
已开发出一种有效且实用的未活化芳基溴化物的短链烷氧基化,特别关注反应的适用性。醇钠用作亲核试剂,相应的醇用作溶剂。该反应既不需要贵金属也不需要有机配体。它使用由溴化铜 (I) 作为催化剂、相应的甲酸烷基酯作为无污染助催化剂和氯化锂作为添加剂组成的催化体系。广泛的底物和测试用例突出了该方法的综合效用。考虑到原料的商业可及性和可负担性,该协议显示出作为可持续制备芳基烷基醚的新替代方案的希望。
