PHOTOCHEMICAL GENERATION OF VINYLKETENES BY ELECTROCYCLIC OPENING OF CYCLOBUTENONES
Hassner, Alfred,Naidorf, Simha
, p. 6389 - 6392 (2007/10/02)
4,4-Dichloro-2-cyclobutenones 1, available by cycloaddition of acetylenes to dichloroketene, can be photolyzed in the presence of olefins or dienes to produce regiospecifically 2-vinylcyclobutanones 3-11.The photochemical reaction succeeds even in some ca
