The reduction of specific disulfides with titanium(III) chloride
The reaction between titanium(III) chloride and disulfides was investigated.Aryl and alkyl disulfides did not react while heterocyclic aromatic disulfides with a nitrogen α to the sulfur were reduced to the corresponding thiols.Products were identified and characterized by nuclear magnetic resonance and inrared spectra; and melting point comparisons with authentic compounds.The reductions occurred only in the presence of citrate and were found to require 2 moles of titanium(III) per mole of disulfide.
