General description
2,4,4,6-Tetrabromo-2,5-cyclohexadienone forms solid charge-transfer molecular complexes with 4-(aminomethyl)piperidine and their spectroscopic characteristics were studied.
Application
2,4,4,6-Tetrabromo-2,5-cyclohexadienone was used as catalyst for efficient deoxygenation of sulfoxides to their corresponding sulfides with 1,3-dithiane. It was also used as reagent for conversion of alcohols to azides.
