An unprecedented protocol for urea synthesis directly from methanol and amine was accomplished. The reaction is highly atom-economical, producing hydrogen as the sole byproduct. Commercially available ruthenium pincer complexes were used as catalysts. In addition, no additive, such as a base, oxidant, or hydrogen acceptor, was required. Furthermore, unsymmetrical urea derivatives were successfully
直接从甲醇和胺合成尿素的空前方案已经完成。该反应是高度原子经济的,产生氢作为唯一的副产物。使用可商购的钌夹钳配合物作为催化剂。另外,不需要添加剂,例如碱,氧化剂或氢受体。此外,通过一锅两步反应成功获得了不对称脲衍生物。
