A new protocol for the synthesis of polychlorinated and polyfluorinated diaryl alkanes via photoredox-catalyzed chloroalkylation of styrenes and subsequent tail-to-tail dimerization was developed. This transformation is achieved using available CF₃CCl₃/CCl₄ as chloroalkylative reagents in the presence of fac-[Ir(ppy)₃] at room temperature, which exhibits a broad substrate scope and excellent tolerance of functional groups.

CF ₃ CCl ₃和CCl _4的光氧化还原催化的氯烷基化和苯乙烯的二聚化

开发了一种通过光氧化还原催化的苯乙烯的氯烷基化反应和随后的尾到尾二聚反应合成多氯和多氟二芳基烷烃的新方案。在室温下，在fac- [Ir（ppy）₃ ]存在下，使用可用的CF ₃ CCl ₃ / CCl ₄作为氯烷基化试剂可以实现这种转化，该反应具有广泛的底物范围和出色的官能团耐受性。
