Generation and detection of a dithia dication derived from 4,9-diethyl[1,4]dihydrodithiino[5,6-f]benzotrithiole 5-oxide and its disproportionation
A dithia dication was generated from 4.9-diethyl[1,4]dihydrodithiino[5,6-f]benzotrithiole 5-oxide on treatment with D2SO4. Hydrolysis of the dication gave 4.9-diethyl [1.4]dihydrodithiino[5.6-f]benzotrithiole 1-oxide and 2-oxide. suggesting that the positive charges, generated on the dithiin ring, transferred to the trithiole ring. A disproportionation of the dithia dication was observed in the solution.
