  • Synthesis Utilizing Reducing Ability of Carbon Monoxide. New Methods for Synthesis of<i>N</i>-Substituted Selenoamides
    作者:Akiya Ogawa、Jun-ichi Miyake、Nobuaki Kambe、Shinji Murai、Noboru Sonoda
    DOI:10.1246/bcsj.58.1448
    日期:1985.5
    selenoamides (2) from nitriles, metallic selenium, carbon monoxide, water, and amines have been developed on the basis of an amino-group-exchange reaction of in situ formed N-unsubstituted selenoamides (1) with primary or secondary amines. The reactions consist of two processes, i.e., the formation of selenoamides 1 by the reaction of nitriles and H2Se formed from selenium, carbon monoxide and water, and the subsequent
    基于原位形成的 N-未取代硒酰胺(1 ) 与伯胺或仲胺。该反应包括两个过程,即通过腈与硒、一氧化碳和水形成的 H2Se 反应形成硒酰胺 1,以及随后 1 与脂肪胺的氨基交换反应。获得的 2 通常足够稳定,可以在 0 °C 的氮气气氛下保持数周而不会出现任何明显的降解。在伯胺的情况下,相应的硒酰胺也可以从腈、硒、一氧化碳、
  • Preparation of Mono-, Di-, and Trisubstituted Ureas by Carbonylation of Aliphatic Amines with <b><i>S</i></b>,<b><i>S</i></b>-Dimethyl Dithiocarbonate
    作者:Rita Fochi、Emma Artuso、Iacopo Degani、Claudio Magistris

    日期:2007.11
    General procedures are reported to prepare N-alkylureas, N,N'-dialkylureas (both symmetrical and unsymmetrical), and N,N,N'-trialkylureas by carbonylation of aliphatic amines, employing S,S-dimethyl dithiocarbonate (DMDTC) as a phosgene substitute. All reactions were carried out in water. Symmetrical disubstituted ureas were prepared directly working at 60 °C with a molar ratio of DMDTC:amine = 1:2
    据报道,通过脂肪胺的羰基化制备 N-烷基脲、N,N'-二烷基脲(对称和不对称)和 N,N,N'-三烷基脲的一般程序,采用 S,S-二硫代碳酸二甲酯 (DMDTC) 作为光气替代品。所有反应均在水中进行。在 60°C 下直接制备对称二取代脲,DMDTC: 胺的摩尔比 = 1:2,优选在氮气下。通过在室温下在第一步中选择性形成的 S-甲基 N-烷基-硫代氨基甲酸酯中间体分两步制备不对称脲。这些中间体在第二步中与氨或各种脂肪胺(伯胺和仲胺)在 50 至 70°C 的温度下发生反应。所有目标尿素均以高产率获得(28 个示例,平均收率 94%)和非常高的纯度(通常 >99.2%)。还需要注意的是回收工业利益的副产品甲硫醇,每摩尔 DMDTC 回收量为两摩尔,同时完全利用试剂。

    Urea derivatives are obtained in mild to good yield from the reactions of primary aliphatic amines with CO2 in the absence of any catalysts, organic solvents or other additives. To optimize reaction conditions, experimental variables including temperature, pressure, the concentration of amine, reaction time etc. were studied. Satisfactory yields were obtained at the optimized conditions that are comparable

  • Organometallic chemistry and catalysis on gold metal surfaces
    作者:Robert J. Angelici
    DOI:10.1016/j.jorganchem.2007.11.023
    日期:2008.3
    As in transition metal complexes, CN–R ligands adsorbed on powdered gold undergo attack by amines to give putative diaminocarbene groups on the gold surface. This reaction forms the basis for the discovery of a gold metal-catalyzed reaction of CN–R, primary amines (R′NH2) and O2 to give carbodiimides (R′–NCN–R). An analogous reaction of CO, RNH2, and O2 gives isocyanates (R–NCO), which react with additional
    像在过渡金属络合物中一样,吸附在金粉上的CN–R配体会受到胺的攻击,从而在金表面上产生假定的二氨基卡宾基团。该反应为发现金金属催化CN–R,伯胺(R'NH 2)和O 2生成碳二亚胺(R'–NCN–R)的反应奠定了基础。CO,RNH 2和O 2的类似反应生成异氰酸酯(R–NCO),该异氰酸酯与其他胺反应生成脲(RNH)2 CO产品。CN-R与仲胺(HNR的金催化反应' 2)和O 2给出混合脲RNH(CO)NR' 2。在另一种金催化的反应中,仲胺HN(CH 2R)2被O反应2经历脱氢的亚胺产物,RCHN(CH 2 R)。特别令人感兴趣的是金粉的高催化活性,否则其以不良的催化性能而闻名。
  • A novel ZrO2–SO42− supported palladium catalyst for syntheses of disubstituted ureas from amines by oxidative carbonylation
    作者:Feng Shi、Youquan Deng、Tianlong SiMa、Hongzhou Yang
    DOI:10.1016/s0040-4039(01)00124-1
    日期:2001.3
    The syntheses of disubstituted ureas by carbonylation of a series of amines in the presence of a sulfate modified zirconia supported palladium catalyst was investigated at an initial total pressure of 4.0 MPa and 135°C. High conversions and yields were achieved for the synthesis of symmetric dialkylureas. This supported catalyst could also be easily separated and recovered after reaction.
