Low-Valent Niobium-Catalyzed Reduction of α,α,α-Trifluorotoluenes FuchibeKohei OhshimaYoshitaka MitomiKen AkiyamaTakahiko 2007 In the presence of 5 mol % of niobium(V) chloride, α,α,α-trifluorotoluene derivatives were reduced with lithium aluminum hydride to give toluene derivatives in good yields. Stepwise, partial reduction of bis(trifluoromethyl)benzene derivative was also demonstrated.
