Synthesis and unusual [2+2] cycloaddition reactions of haloacetylenes activated with the trifluoroacetyl group

Halogenated trifluoroacetylacetylenes have been synthesized for the first time. It was shown that they undergo formally forbidden by the orbital-symmetry rules [2+2] cycloaddition reactions with nonactivated alkenes in the absence of light and catalyst. A possible mechanism for this transformation is suggested.
