ABSTRACT:
Process for the preparation of primary amines of formula (I):where R3 represents an alkyl, cycloalkyl or aralkyl group, by reaction of a triazolium salt of formula (II):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.
