high-yield, and efficient one-pot approach for the synthesis of symmetrically disubstituted ureas from isocyanates in the presence of trimethylsilanol. This novel protocol boasts the use of inexpensive reagents, operational simplicity, excellent yields of products, environmentally friendly conditions, and easy workup. To the best of our knowledge, this is the first example of the synthesis of symmetrically
摘要 我们展示了一种新颖、简便、高产且高效的一锅法,用于在三甲基硅烷醇存在下从异氰酸酯合成对称双取代脲。这种新颖的协议具有使用廉价试剂、操作简单、产品产量高、环境友好和易于处理等优点。据我们所知,这是在三甲基硅烷醇的存在下在一个锅中从异氰酸酯合成对称双取代脲的第一个例子。图形概要
