We have developed a versatile, high-yield synthesis of diarylchloroniums/λ3-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/λ3-chloranes prepared here show unique reactivity in various respects, enabling intermolecular electrophilic arylation reaction of weak nucleophiles, and chlorane-halogane exchange reaction.

二芳基-λ3-氯烷：多功能合成和独特的反应性作为芳基阳离子等价物

我们开发了一种多功能、高产率的二芳基氯鎓/λ3-氯烷合成方法，通过各种氯芳烃与易于制备的四（五氟苯基）硼酸间苯二甲酯在温和条件下反应。反应范围广泛，包括ArCl、ArBr和ArI。这里制备的二芳基氯鎓/λ3-氯烷在各方面都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烷-卤代烷交换反应。
