A New Photochemical Reaction of Unconjugated Thioketones
Tetramethyl-3-thio-1,3-cyclobutanedione ( 1 ) and tetramethyl-1,3-cyclobutanedithione ( 6 ) react with oxygen in the presence of light to yield tetramethyl-1,3-cyclobutanedione ( 2 ). A mechanism involving singlet oxygen is suggested. 1,3-Diphenyl-2-propanethione ( 3 ) undergoes accelerated dimeriza...

| Summary: | Tetramethyl-3-thio-1,3-cyclobutanedione (
1
) and tetramethyl-1,3-cyclobutanedithione (
6
) react with oxygen in the presence of light to yield tetramethyl-1,3-cyclobutanedione (
2
). A mechanism involving singlet oxygen is suggested. 1,3-Diphenyl-2-propanethione (
3
) undergoes accelerated dimerization in the presence of visible radiation to yield tetrabenzyl-1,3-dithietane (
4
). |
