Selenium-catalyzedcarbonylation of nitrobenzene and substituted nitroarenes with CO underatmosphericpressure afforded symmetrical1,3-diarylureas in yields up to 94%. A mechanism has been proposed to demonstrate the formation of symmetrical ureas.
facile synthetic method for ureaderivatives was developed under mild conditions, and contrasts with conventional preparation methods that need highly toxic reagents (phosgene) or severe reaction conditions. In our reaction system, N,N-dimethylformamide or dimethyl sulfoxide as solvent strongly accelerated the carbonylation of primary amines with sulfur under carbonmonoxide (1 atm) at 20 °C to give the
在温和条件下开发了一种新的、简便的尿素衍生物合成方法,与需要剧毒试剂(光气)或苛刻反应条件的常规制备方法形成对比。在我们的反应体系中,N,N-二甲基甲酰胺或二甲基亚砜作为溶剂,在一氧化碳(1 atm)和 20 °C 下强烈加速伯胺与硫的羰基化反应,生成相应的硫代氨基甲酸盐。这些盐在类似温和的条件下很容易被分子氧氧化,以良好至极好的产率提供脲衍生物。这种尿素合成也可以应用于在 N,N-二甲基甲酰胺中使用 1,8-二氮杂双环[5.4.0]undec-7-ene 合成芳族脲的新方法。

In dimethylsulfoxide solution in the presence of excess of powdered sodium hydroxide, N-subsituted trichloroacetamides 1 are used as in situ isocyanate generating reagents which can react with carboxamides or sulfonamides 2 to afford acylureas or sulfonylureas 3.

was developed. With these reactions, an environmentally benign synthesis of urea derivatives could be carried out in good to excellent yields from primary amines and sulfur at ambient pressure of carbonmonoxide and oxy-gen. For example, N, N′-dioctylurea was prepared in 99% yield from two equivalents octylamine and one equivalent sulfur in the presence of carbonmonoxide (1 atm) at 80 °C and oxygen
