Cycloadditions of vinylketenes and ethoxyacetylene
Wuest, James D.
, p. 2291 - 2296 (1980)
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
