A kinetic study of the effect of added HMPA cosolvent on the reaction of 2-lithio-1,3-dithiane (1), bis(phenylthio)methyllithium (2), and bis(3,5-bistrifluoromethylphenylthio)methyllithium (3) with methyloxirane (propylene oxide), N-tosyl-2-methylaziridin

The treatment of S-[3,3-bis(phenylthio)propyl] thioalkanoates with the low-valent titanium species Cp2Ti[P(OEt)3]2 in THF produced 5-substituted 2,3-dihydrothiophenes in good yields. These thiophene derivatives were found to be susceptible to photoirradiation and easily isomerized into 2-alkylidenetetrahydrothiophenes.
Aggregative activation and carbanion chemistry: Complex base deprotonation and directed functionalisation of dithioacetals

Bis(phenylthio)methane and [1,3]-dithiane were efficiently deprotonated by the NaNH2-Et(OCH2CH2)2-ONa complex base. A marked behaviour difference was observed between the sodium carbanion of [1,3]-dithiane and the corresponding lithio-derivative. A 'radicaloid' mechanism is proposed to explain the results observed.
