Selective synthesis of isomeric dithioglycerols
Reactions of 2,3-dibromopropan-1-ol and 1,3-dichloropropan-2-ol with elemental sulfur activated in the system hydrazine hydrate-2-aminoethanol at 30-35°C gave oligomeric polysulfides which were subjected to reductive cleavage with formation of individual dithioglycerol isomers. Activation of sulfur with the use of alkali gives rise to mixtures of isomeric products.

Reduction of thiokols in the system hydrazine hydrate-base as a new route to alkanedithiols
A new procedure for preparative synthesis of alkanedithiols from simple commercially available products is based on reduction of the S-S bond in appropriate polyalkylene disulfides (thiokols) in the system hydrazine hydrate-base. Thiokols were prepared by reaction of dihaloalkanes with Na2S2 or K2S2 generated from elemental sulfur and alkali in aqueous hydrazine hydrate. Reaction of 1,2-dibromocyclohexane with sodium or potassium disulfide yields bis(2-bromocyclohexyl) sulfide as the only product.

STUDIES ON THE REACTION BETWEEN 2,3-DIMERCAPTO-1-PROPANOL AND SELENITE
The reaction between 2,3-dimercapto-1-propanol (DMP) and selenite has been studied.DMP combines with selenite to form moderately stable derivative having an enhanced absorption in the 260-380 nm region.Results obtained from spectrophotometric analysis suggest that the combining molar ratio for DMP to selenite is 3:2.The formation of reaction product is a process dependent on pH.The equilibrium constant of the reaction between DMP and selenite was calculated: K=2.2*1028.The results presented in this paper indicate that sulfhydryl groups of DMP or other thiols affected the decomposition of the reaction product.
