Some fine arynes : Elimination of triflate followed by [2+2] cycloaddition with ketene silyl acetals facilitates the formation of highly strained benzynes with one or two annulated cyclobutane rings. A prominent example based on this chemistry is the synthesis of the novel oxocarbon C 12 O 6 (see structure).
