Se. Bottle et al., NOVEL SULFURATED 5-MEMBERED, 7-MEMBERED AND 9-MEMBERED HETEROCYCLES -UNUSUAL PRODUCTS DERIVED FROM POTENTIAL BISTHIONITROXIDE PRECURSORS, Journal of the Chemical Society, Chemical Communications, (14), 1995, pp. 1449-1450
We report the synthesis of three examples of new classes of sulfurated
heterocycles: dithiadiazaphospholidine 3, benzothiadiazacycloheptene
6a and benzotrithiadiazacyclononene 6b arising from strained cyclic N,
N-disubstituted diazadisulfides (2 and 5) via oxidation or disproporti
onation; single-crystal X-ray structural analyses are reported for the
phospholidine and the benzocycloheptene.
