not react with phosphoryl chloride, however, 2,4-dichloroquinolines and/or 4-chloroquinolin-2-ones are formed in the presence of N,N-dimethylaniline. Along with these compounds, small quantities of novel dihydrogen phosphates of 4-hydroxyquinolin-2-ones were isolated. We outline a simple procedure that allows for the preparation of these compounds in moderate to good yields. All compounds were characterized
3-氯喹啉-2,4-二酮不与磷酰氯反应,但是,在N,N-二甲基苯胺存在下会形成2,4-二氯喹啉和/或4-氯喹啉-2-酮。与这些化合物一起,分离出少量的4-羟基喹啉-2-酮的新型磷酸二氢酯。我们概述了一个简单的步骤,可以以中等到良好的产率制备这些化合物。所有化合物均通过1 H和13 C NMR,IR,EI-MS和ESI-MS光谱进行表征,在某些情况下通过31 P NMR光谱进行表征。
