ABSTRACT:
The invention concerns a process of preparation of the polyazido alcohols by reaction of a polysubstituted oxirane having in position .beta. a nucleofuge group with a metal nitride, characterized in that the reaction is performed in an aqueous medium.
The oxirane formula is: ##STR1## in which X represents a nucleofuge substituent, R1 represents an atom of hydrogen, a lower alkyl group substituted or not by a halogen, an aryl group possibly substituted, R2 and R3 represent an atom of hydrogen, a lower alkyl radical possibly substituted, an aryl group possibly substituted, R4 represents an atom of hydrogen, a lower alkyl group possibly substituted, an aryl group possibly substituted by an alkoxy group. Application to the preparation of polyamino alcohols, ureas, polyazidothiols and binding compositions for propergols.
