Abstract Acid-promoted N [BOND] N bond cleavage in 1, 3-diphenyltriazenes (X-Ph-N= N- NH-Ph-X; X= H, 4-OCH 3), leading to formation of diazonium ions and anilines, is strongly inhibited in aqueous solutions in the presence of cyclodextrins (CDs). The inhibition is ascribed to the formation of inclusion complexes that render the guest diphenyltriazene significantly less basic as a result of the less polar nature of the CD cavity (a microsolvent ...
