Synthesis and Photochemical Transformations of a few 3,3-Bis(4-chlorophenyl)-5-aryl-2(3H)-furanones
A few 3,3-bis(4-chlorophenyl)-5-aryl-2(3H)-furanones were synthesized and their photochemical transformations were studied. On direct irradiation, these aryl substituted 2(3H)-furanones underwent decarbonylation to yield corresponding a,b-unsaturated carbonyl compounds and upon sensitized irradiation, they underwent dimerization arising through a [2+2] cycloaddition reaction.
