We have developed a versatile, high-yield synthesis of diarylchloroniums/λ-chloranes through the reaction of various chloroarenes with readily prepared mesityldiazonium tetrakis(pentafluorophenyl)borate under mild conditions. The scope of the reaction is broad, including ArCl, ArBr, and ArI. The diarylchloroniums/λ-chloranes prepared here show unique reactivity in various respects, enabling intermolecular electrophilic arylation reaction of weak nucleophiles, and chlorane-halogane exchange reaction.
我们开发了一种通过温和条件下各种氯代芳烃与 readily prepared mesityldiazonium tetrakis(pentafluorophenyl)borate 反应制备二芳基氯𬭩/λ-氯仿的通用、高产合成方法。该反应的范围很广,包括 ArCl、ArBr 和 ArI。这里制备的二芳基氯𬭩/λ-氯仿在各个方面表现出独特的反应性,能够实现弱亲核试剂的分子间亲电芳基化反应和氯仿-卤仿交换反应。
