Synthesis and photoreactivity of 4,5-dithienyl[1,3]dithiol-2-ones.
Whereas irradiation of 4,5-dithiophen-2-yl[1,3]dithiol-2-one leads to the expected 2,3,5,6-tetrathiophen-2-yl-1,4-dithiine product, similar reaction of thiophen-3-yl-substituted [1,3]dithiol-2-ones leads to thieno[3,4-c]dithiines via a unique ring cleavage reaction.
