Nickel boride is reported to bring about desulfurization and reductive cleavage of N,N′-diarylthioureas to give corresponding anilines and N-methylanilines while N,N′-dialkylthioureas have been observed to undergo desulfurization to give formamidines; benzimidazoline-2-thiones are reported to undergo desulfurization to benzimidazoles and 1,3-dihydro-1,3-diaryl-2-thioxopyrimidine-4,6(2H,5H)-diones have been observed to yield corresponding hexahydropyrimidine-4,6-diones in high yields in dry methanol at ambient temperature.
镍硼化物被报道能促使N,N′-二芳基
硫脲的脱
硫和还原 cleavage,从而生成相应的
苯胺和
N-甲基苯胺,而N,N′-二烷基
硫脲被观察到可以脱
硫生成甲酰胺;还报道了
