Unsaturated acid chlorides react with mono- and di-substituted alkynes to give a mixture of linear (unsaturated β-chlorovinylketones- and β-chloroallylketones), and cyclic (chloro-5-cyclopentenones and alkylidene-4-cyclopentenones) compounds. These derivatives are produced via carbonium ion rearrangements which result from the first step of the acylation. Experimental conditions and reagent structure
