LiAlH4 for the C–F bond activation of hexafluoropropene, 1,1,3,3,3‐pentafluoropropene, trifluoropropene, chlorotrifluoroethene, and octafluorotoluene. 100 % conversion and TONs up to 155 could be observed for the hydrodefluorination reaction (HDF). For chlorotrifluoroethene hydrodefluorination occurs with high chemoselectivity favoring the C–F bond activation versus C–Cl bond activation.
Cp 3 Ln(Ln = Ce,Nd,Sm,Er,Yb)在LiAlH 4存在下用作六氟丙烯,1,1,3,3,3-五氟丙烯,三氟丙烯的CF键活化的预催化剂,氯三氟乙烯和八氟甲苯。加氢氟化反应(HDF)的转化率为100%,TONs高达155。对于氯三氟乙烯,加氢脱氟反应具有较高的化学选择性,有利于C–F键活化而不是C–Cl键活化。
