WebMar 22, 2024 · The mechanism for a Dess-Martin oxidation reaction in which a secondary alcohol is oxidized to a ketone using Dess-Martin periodinane (DMP). WebThat said, the reagents are cheap (compared to a Dess–Martin, for example), and the reaction is generally very reliable and amenable to use on moderate scales. The DMSO and triethylamine must also be distilled for optimal results (which can be a drawback, especially if large scales are needed). 1. Moffatt oxidation. Reagents: DMSO, DCC, PPA.
Dess–Martin periodinane (DMP) is a chemical reagent used in the Dess–Martin oxidation, oxidizing primary alcohols to aldehydes and secondary alcohols to ketones. This periodinane has several advantages over chromium- and DMSO-based oxidants that include milder conditions (room temperature, neutral pH), shorter reaction times, higher yields, simplified workups, high chemoselectivit…
