Preparation of #alpha#-ketophosphoates by oxidation of #alpha#-hydroxyphosphonates with neutral alumina supported potassium permanganate (NASPP) under solvent-free conditions and potassium permanganate in dry benzene

摘要

Various types of #alpha#-hydroxyphosphonates were converted to #alpha#-ketophosphonates in high yields by potassium permanganate in dry benzene or by neutral alumina supported potassium permanganate (NASPP) under solvent-free conditions.
