A convenient method for the syntheses of benzyl N-alkylcyanocarbamates [III] and N-monoalkylisothioureas [V] have been established. Benzyl N-alkylcyanocarbamates [III] were obtained in high yields by the reactions of the potassium salt of benzyl cyanocarbamate with various alkyl halides. Further, it was found that N-alkyl-S-ethylisothioureas or N-alkyl-S-phenylisothioureas [V] were obtained in good
已经建立了一种合成 N-烷基氰基氨基甲酸苄酯 [III] 和 N-单烷基异硫脲 [V] 的简便方法。N-烷基氰基氨基甲酸苄酯[III]是通过氰基氨基甲酸苄酯的钾盐与各种烷基卤的反应以高产率获得的。此外,发现通过用乙硫醇或苯硫醇处理如此获得的N-烷基氰基氨基甲酸苄酯[III],以良好的收率获得N-烷基-S-乙基异硫脲或N-烷基-S-苯基异硫脲[V]。
