A method for producing sequenced reaction products comprising performing, in one pot, a first reaction at a lower temperature followed by a second reaction at a higher temperature in the presence of a catalyst system comprising a proazahosphatrane in combination with a palladium compound is provided. In one embodiment, the first reaction is a double amination reaction and the second reaction is an arylation. Use of one pot and a single catalyst system for each set of sequential reactions is efficient and economical. Novel N,N-diarylaminostyrenes and N,N-diarylaminostilbenes are produced according to the methods described herein.
提供了一种生产序列反应产物的方法,包括在同一个容器中,在存在包括一种临氨基膦杂环丙胺和钯化合物的催化剂体系的情况下,先在较低温度下进行第一反应,然后在较高温度下进行第二反应。在一个实施例中,第一反应是双胺化反应,第二反应是芳基化反应。对于每组顺序反应使用同一个容器和单一催化剂体系是高效且经济的。根据本文描述的方法生产了新颖的N,N-二芳基氨基苯乙烯和N,N-二芳基氨基苯乙烯。
