Kinetik contra Thermodynamik: Methyl‐Gruppen erhöhen die nucleophile Reaktivität der substituierten Position von Hydrazinen und verringern die Nucleophilie des benachbarten Stickstoff‐Atoms. Infolgedessen ist das tertiäre Stickstoff‐Atom von 1,1‐Dimethylhydrazin 3000‐mal reaktiver als die NH2‐Gruppe, jedoch wird unter thermodynamischer Kontrolle ein NH2‐Proton ersetzt.
