Proton Nuclear Magnetic Resonance Spectroscopy of Bis (Amidinohydrazones) (Bis(Guanylhydrazones)), and Its Use for Studies on the Isomerism and Tautomerism of the Compounds

References

• The compounds are commonly called ‘bis(guanylhydrazones)’. Therefore, their established abbreviations contain the letters GBG preceded by an indication of the substituents (e.g., DE for diethyl or EM for ethyl methyl). The term ‘bis-(amidinohydrazone)’ is, however, more appropriate. The Chemical Abstracts' systematic name of MGBG is 2,2′-(1-methyl-1,2-ethanediylidene)bis(hydrazinecarboximidamide), and other congeners are named analogously
