Some Novel Transformations of 1,4-Dithiafulvenes.

Article abstract of DOI:10.1021/jo00329a020

6-Phenyl-1,4-dithiafulvenes have been substituted at the 6-position by bromo, phenylazo, and nitroso groups; cation radical intermediates are proposed in these reactions.The 6-nitroso derivatives are deoxygenated by phosphines to give products derived from the fragmentation of intermediary nitrenes.
