Allylic dialkoxy disulfides were obtained in good yields and their reactivity has been investigated. Similarly to allylic sulfoxylates, these esters undergo double [2,3]-sigmatropic rearrangement to the appropriate vic-disulfoxides. The latter, being unstable, undergoes spontaneous rearrangement to the corresponding thiosulfonates.

by treatment of symmetrical dialkoxy disulfides (ROSSOR) with alcohols at room temperature has been found. Subsequent spontaneous [2,3]-sigmatropic rearrangements of mixed sulfoxylates such as alkylallyl and alkyl propargyl sulfoxylates afford mixed alkylallyl and alkyl allenesulfinates in good yield. The latter are not readily available by other routes.
