Selective synthesis of isomeric dithioglycerols

Levanova,Grabel'nykh,Sukhomazova,Zemirova,Russavskaya,Albanov,Klyba,Zhanchipova,Korchevin

, p. 1428 - 1433 (2008)

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.
