PROCESS FOR THE PREPARATION OF DIAZIRIDINES AND THEIR DERIVATIVES

Process for preparing N,N'-dialkyldiaziridines or bicyclic diaziridines of the general formula I or II: (I) or (II) where R1 and R2 are each alkyl or aryl, A is a substituted or unsubstituted one-membered carbon bridge and B is a substituted or unsubstituted three-membered methylene bridge, by reacting a mixture of two moles of a monoamine or one mole of a 1,3-diamine with one mole of an aldehyde or ketone at 25 DEG -70 DEG C., preferably 40 DEG -50 DEG C., while thoroughly mixing with one mole of an aqueous solution of an alkali metal or alkaline earth metal salt of hypochlorous acid and extracting with an organic solvent, preferably chloroform, from the reaction mixture, as well as bicyclic diaziridines which have 1,3-diazabicyclo-[3.1.0]-hexane as basic structure and are prepared using 2,2-dimethyl-1,3-propylenediamine.
