Dess–Martin periodinane: Dess–Martin periodinane (DMP) is a chemical reagent used to oxidize 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 chemoselectivity, tolerance of sensitive functional groups, and a long shelf life.  It is named after the American chemists Daniel Benjamin Dess and James Cullen Martin who developed the reagent in 1983.  It is based on IBX, but due to the acetate groups attached to the central iodine atom, DMP is much more reactive than IBX and is much more soluble in organic solvents.
