Telescopic Synthesis of Azo Compounds via Stable Arenediazonium Tosylates by Using n-Butyl Nitrite as Diazotization Reagent
A multi-step catalyst-free synthesis of azo compounds by using n-butyl nitrite as a diazotization reagent and p-toluene sulfonic acid as a mild acidic agent in ethanol/water mixed solvent was investigated. In the combined one-pot synthesis process, no nitrous acid was produced during the diazotizati...
