Inhoud:
Reaction of 1-(2,3,4,5-tetra-o-acetylgalactaroy1)bis-2-[thiomethyl or thiobenzy1(thiocarbony1)]hydrazine 1 or 2 with different bifunctional amines [piperazine (PPZ), tetraethyl-ethylenediamine (TEED), tetramethylethylenediamine (TMED), and tetramethyl propanediamine (TMPD)] at different hydrazide/diamine ratios in methanol, gave the corresponding monomeric and polymeric bis-hydrazide salts. Elucidation of the structures of compounds prepared are discussed and mechanistic pathways for their formation are proposed.
