Oxidation of Primary Alcohol to Aldehyde

RCH2OH + [O] → RCHO + H2O

개요

Primary alcohols are oxidized to aldehydes using mild oxidizing agents like PCC or Dess-Martin periodinane. Stronger oxidants (KMnO₄, CrO₃) would over-oxidize to the carboxylic acid. The carbon oxidation state changes from -1 to +1. Distilling the aldehyde product during reaction prevents over-oxidation.
