  meta-substituted carboxylates are converted into para-substituted alkoxyarenes and vice versa. The combined processes provide a convenient synthetic entry to the important class of aromatic ethers from widely available carboxylic acids. A silver/copper bimetallic catalyst system promotes the decarboxylative Chan–Evans–Lam alkoxylation of ortho-substituted aromatic carboxylate salts with tetraalkyl orthosilicates

  摘要 银/铜双金属催化剂体系可促进原位取代的芳族羧酸盐与原硅酸四烷基酯或硼酸三芳基酯的脱羧化Chan-Evans-Lam烷氧基化反应。非邻位取代的羧酸盐通过邻-C-H-烷氧基化被烷氧基化，同时羧酸酯导向基团通过原脱羧作用被裂解。这样，间位取代的羧酸盐被转化为对位取代的烷氧基芳烃，反之亦然。组合的方法可以从广泛使用的羧酸中方便地合成进入重要类别的芳族醚。 银/铜双金属催化剂体系可促进原位取代的芳族羧酸盐与原硅酸四烷基酯或硼酸三芳基酯的脱羧化Chan-Evans-Lam烷氧基化反应。非邻位取代的羧酸盐通过邻-C-H-烷氧基化被烷氧基化，同时羧酸酯导向基团通过原脱羧作用被裂解。这样，间位取代的羧酸盐被转化为对位取代的烷氧基芳烃，反之亦然。组合的方法可以从广泛使用的羧酸中方便地合成进入重要类别的芳族醚。

  日期：——

  Efficient C–N and C–O coupling reactions of aryl halides with amines and alcohols have been developed by using the strategy of heterogeneous visible light photoredox and nickel dual catalysis. Obviously, the joint use of inexpensive and bench-stable CdS and nickel salts, together with mild reaction conditions, makes these two transformations attractive for the synthetic community. This heterogeneous
