The TBADT‐catalyzed C(sp³)–H functionalization of perfluorophenyl‐ and perfluoroalkyl‐substituted alkanes was investigated. Alkylation of alkanes having a perfluoroalkyl group and alkyl‐substituted perfluorobenzenes avoided α‐C–H bonds. Radical polar effects in the S_H2 transition states could explain this avoidance of α‐C–H functionalization.

使用钨酸盐光催化剂的极性效应驱动的氟化烷烃的位点选择性C（sp ³）–H功能化

研究了TBADT催化的全氟苯基和全氟烷基取代的烷烃的C（sp ³）–H官能化。具有全氟烷基的烷烃和烷基取代的全氟苯的烷基化可避免α-CH键。S _H 2过渡态中的自由基极性效应可以解释这种对α-CH-H功能化的避免。
