Catalytic hydrodefluorinations of organofluorine compounds by low-valent niobium catalyst were developed. In the presence of niobium(V) chloride (typically, 5 mol%), fluorobenzenes, α,α,α-trifluorotoluenes and (trifluoromethyl)pyridines were hydrodefluorinated with lithium aluminum hydride to give the corresponding benzenes, toluenes and methylpyridines in good yields, respectively.
研究了低价铌催化剂对有机氟化合物的催化加氢脱氟化氢反应。在氯化铌(V)(通常为5 mol%)的存在下,用氢化铝锂将氟苯,α,α,α-三氟甲苯和(三氟甲基)吡啶加氢脱氟化氢,以高收率得到相应的苯,甲苯和甲基吡啶,分别。
