DETECTION AND DECOMPOSITION OF DI-TERT-BUTYL DISULFIDE-POLYOXIDE DERIVATIVES

The chemistry of di-tert-butyl disulfide polyoxide derivatives has been investigated. Low-temperature experiments permit the clear detection of vic-disulfoxides (alpha-disulfoxides). In addition, a proposal for a decomposition mechanism that accounts for the detection of one of the diastereoisomers and the formation of the final products has been advanced. The formation of di-tert-butyl thiosulfonate was also shown to be solvent and concentration dependent. Finally, low-temperature experiments permit the detection of the sulfinyl sulfone and vic-disulfone derivatives. A general mechanism has been proposed for the decomposition of these disulfide polyxoide derivatives.
