Di-t-butyl disulfide

EXTEN SIONS AND COMMENT ARY The three-carbon analog of 2C-T-9 (this would be one of the ALEPH series) has never been made and, for that matter, none of the hi gher numbered 2C-T s have had the amphetamine counterpart s synthesized. They are, as of the present time, unknown compounds. This nifty reaction with di-(t)-butyl disulfide worked so well, that three additional disulfides that were at hand were immediately thrown into the chemical program, with the quick assignment of the names 2C-T-10, 2C-T-11, and 2C-T-12.

Another kind of evidence for the involvement of ion radicals in photo-oxidation ccmies from the observation of cleavage of certain sulfides (41) with formation of unoxidized disulfides. Unlike the benzyl alkyl sulfides (40). di-t-butyl sulfide gives on oxidation with several photosensitizers, in addition to the sulfoxide and sulfone, amounts of di-t-butyl disulfide varying from traces with rose bengal or methylene blue in methanol to 97 and 100% in acetone with rose bengal free and bound on polymer beads, respectively. The yield of the disulfide may be a measure of the relative rate at which the cation radical 1 dissociated to the t-butyl cation and the t-butylthiyl radical in the various media ... 

For the sulfenylation of the less strongly basic ketone-enolates the more reactive thiosulfonates R"SS02R", thiocyanates R"SC=N or sulfenyl halides R"SC1 (or Br), may be used instead of dialkyl disulfides. In many cases, however, the reaction with the more easily obtainable disulfides is sufficiently fast. Di-tcrt-butyl disulfide, t-BuSS-f-Bu reacts very sluggishly, even with the most strongly basic organometallics.

Di-t-butyl sulfide could be converted to disulfide in two hours at room temperature by trls-(p-bromophenyl)-aminium fluoborate in a stream of oxygen, but neither tetrahydrothiophene nor diphenyl sulfide underwent cleavage under these conditions.
