Abstract
Mannose, galactose and glucose thiosemicarbazones, and mannose thiocar bohydrazones exist in DMSO solutions as tautomeric mixtures of pyranos e and linear hydrazone forms, but in solutions of galactose and glucos e thiocarbohydrazones there are also hexahydro-1,2,4,5-tetrazine-3-thi one tautomers.
