Abstract
Reactions of 2-halo-2-alkenals R ''(R')C=CX-CHO with secondary amines R(2)NH occur as ipso-substitution of the halogen atom, along with frag mentation and condensation, yielding 1,2-diaminoethenes R(2)NCH=CHNR(2 ), carbonyl compounds R '' C(O)R', 1,3-bis(amino)-2-haloolefins R ''(R ')C(NR(2))CX=CHNR(2), and formamides R(2)NCHO. The ratio between the c ompeting reactions depends on the structure of the starting compounds and the experimental conditions.
