Abstract
The reaction of cyclic polysulfides, such as 5H-1,2,3,4-benzotetrathiepin and 6H-1,2,3,4,5-benzopentathiocin as the sulfuration reagent with relatively stable phosphorus ylides affords efficiently thiocarbonyl compounds such as thioaldehydes and thioketones, which further react with 2,3-dimethyl-1,3-butadiene or cyclopentadiene in situ to give various 5,6-dihydro-2H-thiopyrans and 2-thiabicyclo[2.2.1]hept-5-enes in satisfactory yields.
