Abstract
By cycloaddition reactions of the title compounds 1, new spiro[1,3-dit hiole-thiopyran] derivatives 3 and 5 are available. Their cleavage wit h mercury(II) acetate leads to the corresponding bicyclic thiopyran-4- ones 9 and 10. Starting from ,6H-[1,2]dithiolo[4,3-c][1,2]dithiole-3,6 -dithione (1d), besides 5',4'',5''-octa-(methoxycarbonyl)thiopyrano[3, 2-b] 2'-(1',3'-dithiole)-8-spiro-2''-(1'',3''-dithiole) (5), the tetra (5',6'-methoxycarbonyl-1', -k]-1,2,7,8-tetrathiacyclododeca-3,5,9,11-t etraene (8) is formed.
