The synthesis of a series of new pyridine aminomethylphosphinic acids is described. These compounds were obtained in the reaction of the corresponding pyridine aldehydes with primary amines and with ethyl phenylphosphinate, or methylphosphinate, in the presence of bromotrimethylsilane. In aqueous, strong acid solutions, pyridine aminophosphinic acids were split, forming the phenyl-, or methylphosphonic
描述了一系列新型吡啶氨基甲基次膦酸的合成。这些化合物是在相应的吡啶醛与伯胺和苯基次膦酸乙酯或甲基次膦酸在溴代三甲基硅烷存在下的反应中获得的。在强酸水溶液中,吡啶氨基次膦酸被分解,形成苯基或甲基膦酸和相应的仲吡啶基烷基胺。测量了一些观察到的裂解的动力学,并提出了裂解的机制。
