The present invention relates to a cyanoethylmelamine derivatives of the formula I:
wherein 1 to 5 of the substituents X' to X6 represent a cyanoethyl group and at least one remaining group represents a C1-20 alkyl group, a C2-20 alkenyl group (said alkyl or alkenyl group may optionally have an alicyclic group or a phenyl group in its structure), a C5-6 cycloalkyl group or a phenyl group, or two of the substituent groups bonded to the same nitrogen atom together may form an alkylene chain having 2 to 7 carbon atoms, and the remaining substituent or substituents represents a hydrogen atom}. The production of cyanoethylmelamine derivatives can be obtained at high yield by reacting N-substituted melamine derivatives with acrylonitrile or reacting mono- or di-halogeno-N-substituted triazine derivative with aminopropionitrile. The compounds of the formula (I) are useful compounds as intermediates for fine chemicals such as agricultural chemicals, medicines, dye stuffs, paints, etc. and as crosslinking intermediates for resins.
本发明涉及一种公式I的氰乙基三聚氰胺衍生物:其中取代基X'至X6中的1至5个代表氰乙基基团,至少一个剩余基团代表C1-20烷基基团,C2-20烯基基团(该烷基或烯基基团的结构中可能含有环烷基或苯基),C5-6环烷基基团或苯基,或两个结合到同一氮原子的取代基团可共同形成具有2至7个碳原子的烷基链,其余的取代基或取代基团代表氢原子}。通过将N-取代三聚氰胺衍生物与丙烯腈反应或将单取代或双卤代N-取代三嗪衍生物与氨基丙腈反应,可以高产率地获得氰乙基三聚氰胺衍生物。公式(I)的化合物是作为农药、药物、染料、涂料等精细化学品的中间体以及树脂的交联中间体的有用化合物。
