, p. 1849 - 1852 (1985)
The title reaction furnished the yellow 3,4-dicyano-2,5-bis(diphenylmethyleneamino)-thiophene and a red precursor which contains one more sulfur atom; structures and mechanism are discussed.
Unusual formation of a thiacyclopent-2-ene by the reaction of 4,4′-dimethoxythiobenzophenone with tetracyanoethylene

The reaction of 4,4′-dimethoxythiobenzophenone (1a) with tetracyanoethylene (TCNE) afforded an unusual type of 2:1 adduct with the structure of thiacyclopent-2-ene (5a). On the other hand, the reaction of thiobenzophenone (1b) with TCNE afforded the corresponding thiophene, the normal 2:1 adduct (2b). The mechanism of the formation of 5a is discussed.
