Process for the preparation of primary amines of formula (I): on enclosed where R3 represents an alkyl, cycloalkyl or aralkyl group, by reaction of a triazolium salt of formula (II): (formula see on enclosed paper version) where R1 and R2 represent hydrogen or an alkyl, aralkyl or aryl group, R4 represents an alkyl or aralkyl group or a residue of an organic polymer functionalized by an alkylating group, and A- represents a halogen, alkylsulphonate, arylsulphonate, alkyl sulphate, hydrogensulphate, hemisulphate, perchlorate or hydroxide, with a hydride, in order to obtain an amine of formula (I), which is isolated, if desired, and intermediates.
制备式(I)的主要胺的过程:通过将式(II)的三唑盐与氢化物反应(式子见附上的纸张版本),其中R1和R2代表氢或烷基、芳基烷基或芳基,R4代表烷基或芳基烷基或被烷基化基团功能化的有机聚合物残基,A-代表卤素、烷基磺酸盐、芳基磺酸盐、烷基硫酸盐、氢硫酸盐、半硫酸盐、高氯酸盐或氢氧化物,其中R3代表烷基、环烷基或芳基烷基。最终得到式(I)的胺,可隔离,如果需要,还有中间体。
