RING EXPANSION REACTIONS OF 1,3-DITHIOLANS AND 1,3-DITHIANS. A NEW SYNTHESIS OF DIHYDRO-1,4-DITHIINS AND DIHYDRO-1,4-DITHIEPINS

Francisco, Cosme G.,Freire, Raimundo,Hernandez, Rosendo,Salazar, Jose A.,Suarez, Ernesto

, p. 1621 - 1624 (1984)

A mild and convenient method for ring expansion of 1,3-dithiolans and 1,3-dithians to dihydro-1,4-dithiins and dihydro-1,4-dithiepins, respectively, using phenyl selenenyl chloride in methylene chloride is described.A mechanism involving sulphenyl chloride derivatives as intermediates is proposed.
