REACTION OF α-α'-DICHLORO-SUBSTITUTED 1,5-DIKETONES WITH AMMONIA AND AMMONIUM ACETATE
Kharchenko, V. G.,Chalaya, S. N.,Litvinov, O. V.
, p. 291 - 293 (1985)
Under the influence of ammonia or ammonium acetate, α-α'-dichloro-substituted 1,5-diketones undergo heterocyclization to give β-chloropyridines or 2-benzoylpyrrole derivatives.The structure of the final product depends on the reagent and the character of
CYCLIZATION OF 2,4-DICHLORO-1,5-PENTANEDIONES WITH NUCLEOPHILIC REAGENTS
Litvinov, O. V.,Chalaya, S. N.,Kharchenko, V. G.
, p. 878 - 882 (2007/10/02)
The mechanism of reaction of 2,4-dichloro-1,5-pentanediones with ammonia has been studied.Intramolecular cyclization of the intermediate resulting from nucleophilic attack at the carbonyl group can occur in two ways, depending on the reaction conditions,
