Oxone (Potassium peroxymonosulfate, 2KHSO5·KHSO4·K2SO4)

Mechanism + Description

Depends on catalysts and additives present

General comments

Oxone is often used as a co-oxidant or terminal oxidant with various metal and non-metal catalysts. This material can oxidize alcohols to aldehydes and ketones alone, but over oxidation is often an issue. Whilst this reagent has a high mol wt hence poor atom economy, it is cheap, and the by-products are innocuous.
