摘要

Catalytic hydrodefluorinations of organofluorine compounds by low-valent niobium catalyst were developed. In the presence of niobium (V) chloride (typically, 5mol%), 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.
