, p. 847 - 850 (2007/10/02)
The reaction of a series of 2,5-dihydrothiophenes with benzyne, generated from 2-carboxybenzenediazonium chloride, affords 1-phenylthio-1,3-dienes in good yields through the fragmentation of sulfonium ylide intermediates.
GENERAL SYNTHESIS OF POLYSUBSTITUTED THIOPHENES FROM DIKETO SULFIDES

, p. 1983 - 1984 (2007/10/02)
Treatment of diketo sulfides with a low-valent titanium reagent at 0 deg C (in two cases at room temperature) affords 3,4-dihydroxythiolanes in good yields.The acid-catalyzed (p-toluenesulfonic acid) dehydration of the latter compounds leads to the corres
REGIOCHEMISTRY OF THERMAL EXTRUSION OF SULFUR FROM 2,6-DIARYL-1,4-DITHIINS YIELDING 2,5- AND 3,4-DIARYLTHIOPHENES
Nakayama, Juzo,Shimomura, Masahiro,Iwamoto, Michiko,Hoshino, Masamatsu
, p. 1907 - 1910 (2007/10/02)
The predominant formation of 2,5-diarylthiophenes over the 3,4-diaryl isomers by thermolyses of a series of 2,6-diaryl-1,4-dithiins supports that this sulfur extrusion reaction proceeds by the mechanism involving the valence isomerization to thiocarbonyl
