A highly efficient strategy to synthesize completely unsymmetrical triarylmethanes promoted by iodine under metal-free conditions has been successfully developed. Three different aryl groups were introduced into triarylmethanes in a one-pot reaction from inexpensive and readily available salicylaldehydes, arylboronic acids and arenes via o-QM intermediates generated in situ, delivering a wide range of unsymmetrical triarylmethanes bearing various functional groups in good yields with excellent chemoselectivity.

无金属碘促进的不对称三芳基甲烷的直接合成

在无金属条件下，成功开发了一种高效的策略来合成由碘促进的完全不对称的三芳基甲烷。通过廉价的易得的水杨醛，芳基硼酸和芳烃，通过现场生成的o -QM中间体，通过一锅反应将三个不同的芳基基团引入三芳基甲烷中，从而以良好的收率和良好的收率提供了多种带有各种官能团的不对称三芳基甲烷。化学选择性。
