Nucleophilic reactions at the sulfur of thiiranium and thiirenium ions. New insight in the electrophilic additions to alkenes and alkynes. Evidence for an episulfurane intermediate

The thiiranium hexachloroantimonates 1a, 3, and 5a-c and the thiirenium hexachloroantimonates 6a-c and 7a with exocyclic S-R substituent (R = Me, Et, i-Pr) react at sulfur with dialkyl disulfides R″SSR″ (R″ = Me, Et and R″ ≠ R) in CD2Cl2 at 25°C to give S-R″ substituted ions. The reaction rates are affected by the steric hindrance of the substituents at sulfur and at ring carbons. t-2,t-3-Di-tert-butyl-r-1-methylthiiranium hexachloroantimonate (2) does not react, and the t-2-tert-butyl-c-3-phenyl-r-1-methylthiiranium (5a) reacts about 100 times faster than the c-2,t-3-di-tert-butyl-r-1-methylthiiranium ion (1a). The analysis of the kinetic data suggests that the sulfonium sulfur undergoes attack by the disulfide in the ring plane from a direction that is parallel to the C-C ring bond. This is also the direction which ensures the maximum overlap with the LUMO of thiiranium or thiirenium ions (determined at the RHF/3-21G*//RHF/3-21G* level). The combined consideration of the approach modality and of the maximum orbital overlap suggests that the nucleophilic substitution at sulfonium sulfur is not an SN2-like reaction but occurs via an intermediate with episulfurane-like structure. The principle of microscopic reversibility will dictate that this is also the first intermediate in the electrophilic sulfenylation of unsaturated C-C bonds.

NEW SIMPLE SYNTHESIS OF UNSYMMETRICAL DISULFIDE

Unsymmetrical disulfides from the co-photolysis of mixtures of symmetrical alkyl disulfides is reported.Rates have been obtained for 35 combinations of C2 to C10 alkyl disulfides and their isomers.An equilibrium is attained after relatively short irradiation periods in cyclohexane.

Reaction of thiyl radicals. XIII. Photochemically induced exchange reactions of liquid alkyl disulfides

The liquid phase photolysis of some 35 liquid alkyl disulfide mixtures has been studied.The corresponding unsymmetrical disulfide is the only significant product of the reaction and the system attains a photo-equilibrium state at longer exposure times.Product formation is completely eliminated by the addition of nitric oxide.Quantum yields have been redetermined for the methyl disulfide- ethyl disulfide system using four different light sources.Initial rates have been measured for each of the 35 combinations and have been shown to be a function of total molecular weight of the disulfide mixture and to be strongly influenced by steric factors.These effects are most pronounced for mixtures wherein the exchange reaction between thiyl radical and a symmetrical disulfide is important as indicated by quantum yields above unity.Combinations of isodisulfides give rise to anomalously high rates.
