tert-Butyl hypochlorite is the organic compound with the formula (CH3)3COCl. A yellow liquid, it is a rare example of an organic hypochlorite, i.e. a compound with an O-Cl bond. It is a reactive material that is useful for chlorinations. It can be viewed as a lipophilic version of sodium hypochlorite (bleach).[1]

Synthesis and reactions

[edit | edit source]

It is produced by chlorination of tert-butyl alcohol in the presence of base:[2][3]

(CH3)3COH + Cl2 + NaOH → (CH3)3COCl + NaCl + H2O

tert-Butyl hypochlorite is useful in the preparation of organic chloramines such as chloramine-T:[4]

R2NH + t-BuOCl → R2NCl + t-BuOH
