Chemistry – A European Journal, EarlyView.Strategic electronic matching between imidazolium salts and aryldiazonium salts enables a chromatography‐free route to versatile azoimidazolium scaffolds. Fine‐tuning the substituents unveils a powerful dichotomy: strong ─OMe resonance stabilizes highly persistent neutral aminyl radicals (up to 3 weeks), whereas the superior ─NMe2 donor strength yields
