A new simple synthesis of cis- and trans-3,5-di-tert-butyl-3,5-diaryl-1,2,4-trithiolanes from ketones and tetraphosphorus decasulfide
Abstract
The reaction of pivalophenones with tetraphosphorus decasulfide afforded cis- and trans-3,5-di-tert-butyl-3,5-diaryl-1,2,4-trithiolanes, which equilibrated to give other isomers in refluxing toluene via thiopivalophenones and thiopivalophenone S-sulfides.
