The titanium tetrachloride‐catalyzed hydrodefluorination reaction of trifluorotoluene derivatives was developed using triethylsilane as the reducing agent. The reaction produced various toluene derivatives with high chemoselectivities by means of readily accessible reagents. This hydrodefluorination process was extended to the intramolecular Friedel–Crafts benzylation reaction, furnishing polycyclic
以三乙基硅烷为还原剂,开发了四氯化钛催化的三氟甲苯衍生物的加氢脱氟反应。该反应通过容易获得的试剂产生了具有高化学选择性的各种甲苯衍生物。这种加氢脱氟过程已扩展到分子内Friedel-Crafts苄基化反应,从而以良好的收率提供了各种环大小的多环芳族化合物。
