A method for producing compounds of formula (I) in which the radical R1 is selected from —NH2, —NH2-zAz, and monovalent alkyl and aryl radicals, the radicals A are selected in each case independently of one another from the phosphoryl radicals DOPO-, DPhPO- and DPhOPO-, and the indices x, y and z, in each case independently of one another, stand for 0 or 1, wherein at least one of the indices is ≠0, by reacting, in a first step, melamine or, when R1 is an alkyl or aryl radical, the corresponding alkyl or aryl guanamine, with one or more of the corresponding phosphinyl chlorides DOP-CI, DPhP-Cl and DPhOP-CI, in order to bond one or more phosphinyl radicals to the amino groups(s) of the melamine or guanamine, and in a second step oxidizing the phosphinyl radical(s) by reaction with an oxidizing agent to give the corresponding phosphoryl radical(s).
一种生产式(I)化合物的方法,其中基团R1从—NH2,—NH2-zAz和一价烷基和芳基基团中选择,基团A在每种情况下独立地从磷酰基团DOPO-,DPhPO-和DPhOPO-中选择,指数x,y和z在每种情况下独立地代表0或1,其中至少一个指数不等于0,通过在第一步中,将三聚氰胺或当R1为烷基或芳基基团时,将相应的烷基或芳基胍三聚体与一个或多个相应的磷酰氯DOP-CI,DPhP-Cl和DPhOP-CI中的一个或多个反应,以将一个或多个磷酰基团连接到三聚氰胺或胍三聚体的氨基团,并在第二步中通过与氧化剂反应氧化磷酰基团,从而得到相应的磷酰基团。
