Cycloadditions of vinylketenes and ethoxyacetylene

Two major adducts are formed when diarylketenes react with ethoxyacetylene: cyclobutenones, produced by 2+2 cycloadditions characteristic of all ketenes, and norcaradienes, the unexpected products of 2+2+2 cycloadditions. Simpler vinylketenes in which the vinyl group is not incorporated in an aromatic ring yield only products derived from 2+2 cycloadditions.
