outcome of reaction of sodium N-benzylideneglycinate containing water in its crystal lattice with dialkyl chlorophosphites depends on the mode of addition of the latter. Upon the simultaneous mixing of the reactants, 1,4-bis[α-(dialkoxyphosphoryl)benzyl]piperazine-2,5-diones are formed from two molecules of each reactant. With the slow addition of dialkyl chlorophosphite, the main reaction product is
N-亚苄基次甘氨酸钠在其晶格中的水与亚磷酸二烷基酯的反应结果取决于后者的添加方式。当反应物同时混合时,由每种反应物的两个分子形成1,4-双[α-(二烷氧基磷酰基)苄基]哌嗪-2,5-二酮。在缓慢加入亚磷酸二烷基酯的情况下,主要反应产物为2- 3- [α-(二烷氧基磷酰基)苄基] -5-氧代-2-苯基咪唑啉-1-基}乙酸('1:2加合物'),其形成包括二烷氧基磷酰基部分的1,4-迁移。
