desirable condition without using tedious and toxic workup processes at a low temperature (37 °C for aliphatic amines and 60 °C for aniline derivatives), as well as by embracing the broad scope of products in good to high yields even with weak nucleophiles such as aniline. A proposed acid-activated mechanism was suggested for the model reaction that was further confirmed by detecting ammonia as the leaving

An indium triflate-catalyzed synthesis of primary carbamates from alcohols and urea as an ecofriendly carbonyl source has been developed. Various linear, branched, and cyclic alcohols were converted into the corresponding carbamates in good to excellent yields. This method also provided access to N-substitutedureas by carbamoylation of amines. All the products were obtained by simple filtration or
已经开发出一种三氟甲磺酸铟催化的醇和尿素合成伯氨基甲酸酯,作为一种环保的羰基来源。各种直链、支链和环状醇以良好到极好的收率转化为相应的氨基甲酸酯。该方法还通过胺的氨基甲酰化提供了获得 N-取代脲的途径。所有产品均通过简单过滤或结晶得到,无需色谱纯化。机理研究表明,氨基甲酰化反应是通过与铟的 O 配位活化尿素进行的,然后是醇或胺对尿素羰基中心的亲核攻击。原料和催化剂廉价易得,反应时间短,
