Alcohol to azide

WebDec 18, 2015 · I really want to shout this at every first year organic chemistry student. You could get $\mathrm{S}_{N}1$ or $\mathrm{E}1$ for a tertiary alcohol. The primary alcohol might undergo $\mathrm{S}_{N}2$, but there's a good chance that it will be a bad reaction. Your best bet would be to convert the primary alcohol into a tosylate. $\endgroup$ – WebJan 23, 2024 · Sodium azide (0.60 g, 9.1 mmol) was added portionwise over 20 min to a solution of cis-bicyclo [3.3.0]octane-3,7-dione (1.0 g, 7.2 mmol) in 36% aqueous HCl (20 mL), while keeping the temperature below 35 °C.
