The efficient, mild, and semiheterogeneous decarboxylative cross-coupling of a variety alkyl carboxylic acids with aryliodides has been accomplished through a merger of TiO2 photoredox and nickel cross-coupling chemistries. The protocol is tolerant to a wide range of substituted aryliodides and alkyl carboxylic acids. Through replacement of the commonly employed Ir transition-metal complexes with
各种烷基羧酸与芳基碘化物的高效,温和和半均质的脱羧交叉偶联已经通过TiO 2光还原和镍交叉偶联化学的结合来实现。该方案可耐受多种取代的芳基碘化物和烷基羧酸。通过用P25 TiO 2作为光催化剂代替常用的Ir过渡金属配合物,我们表明这些转变可以被异质化,而对这些转变的效率几乎没有影响,同时由于可重复使用性和可回收性而降低了相关成本。 TiO 2光催化剂的廉价性质。
