  未活化芳基溴的实用无配体铜催化短链烷氧基化

  摘要：

  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。

  日期：1996.7

  mixture of ten aryloxides and heteroaryloxides. The feasibility of generating combinatorial libraries containing aryl and heteroaryl ethers was demonstrated by reacting the resin's with a single electrophile (n-butyl bromide) to afford mixtures of ether products. The advantages of using quaternary ammonium exchange resins over solution phase chemistry to prepare this library are discussed.

  季铵交换树脂（的Amberlite ® IRA-900）中制备每个含有10芳氧基和heteroaryloxides的混合物。通过使树脂与单一的亲电子试剂（正丁基溴化物）反应以提供醚产物的混合物，证明了生成包含芳基和杂芳基醚的组合库的可行性。讨论了使用季铵交换树脂优于溶液相化学制备该文库的优点。

  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
