摘要: Resume L'action de chlorures d'acides α-ethyleniques sur des alcynes vrais et bisubstitues conduit a un melange produits lineaires (β-chlorovinylcetones β-chloroallylcetones ethyleniques) cycliques (chloro-5 cyclopentenones alkylidene-4 cyclopentenones). Plusieurs composes se forment par rearrangements carbocations issus la premiere etape d'acylation l'orientation transpositions est gouvernee les conditions experimentales structure reactifs depart. La synthese fait ainsi dans tres satisfaisantes.
