HALOGENATION OF HETEROCYCLIC ACETYLENIC MONO- AND DIAMINES
Kurbanov, A. I.,Turgunov, E.,Sirlibaev, T. S.
, p. 1135 - 1137 (1988)
Cyclic acetylenic monoamines, synthesized by the decomposition of the corresponding acetylenic aminoalcohols, and diamines, obtained by the Mannich reaction, give the products of the monoaddition of the halogens at the triple bond in aqueous solutions of acids.
