  • METHOD FOR SYNTHESIZING AN N-UNSUBSTITUTED OR N-SUBSTITUTED AZIRIDINE
    Publication number: 20100191000
    Abstract: Process for preparing an N-unsubstituted or N-substituted aziridine of the formula which comprises reacting an olefin of the formula I where R1 to R5 are each, independently of one another, hydrogen, a linear or branched alkyl radical having from 1 to 16 carbon atoms, a hydroxyalkyl radical having from 1 to 4 carbon atoms, a cycloalkyl radical having from 5 to 7 carbon atoms, a benzyl or phenyl radical which in each case may be substituted in the o, m or p position of the phenyl radical by methoxy, hydroxy, chlorine or alkyl radicals having from 1 to 4 carbon atoms and the radical R1 or R2 together with the radical R3 or R4 may be closed to form a 5- to 12-membered ring or the radicals R1 and R2 may be closed to form a 5- to 12-membered ring, with ammonia or a primary amine of the formula R5NH2 in the presence of iodine or bromine.
