SPIRO 1,3,4,6-TETRATHIAPENTALENE-2-THIONES

Reaction of the geminal alpha,alpha-dichloroketones (3) and (5) with the 4,5-dimercapto-1,3-dithiole-2-thione dianion (2) yields the spiro 1, 3,4,6-tetrathiapentalene-2-thiones (4) and (6). The structure of 1,3,4,6-tetrathiapentalene-2-thione-5-spiro-3'-benzo[c]furan-1'-(3H)-one (4) was de...

Summary:Reaction of the geminal alpha,alpha-dichloroketones (3) and (5) with the 4,5-dimercapto-1,3-dithiole-2-thione dianion (2) yields the spiro 1, 3,4,6-tetrathiapentalene-2-thiones (4) and (6). The structure of 1,3,4,6-tetrathiapentalene-2-thione-5-spiro-3'-benzo[c]furan-1'-(3H)-one (4) was determined by X-ray crystallography.
