We reported a new synthesis of 2-aryl-2H-indazoles via a silver-catalyzed [3+2]-cycloaddition of benzynes with diazocarbonyl reagents. We postulate that this transformation involves the generation of (1H-indazol-1-yl)silver to activate a subsequent arylation with the second benzyne.
我们报道了一种通过银催化的苯炔与重氮羰基试剂的[3+2]-环加成反应合成 2-芳基-2H-吲唑的新方法。我们推测，这种转化涉及（1H-吲唑-1-基）银的生成，以激活随后与第二个苯炔的芳基化反应。
