摘要: An organic oxidation catalyst for alcohols which is environmentally less harmful and with which efficient oxidation can be conducted. The oxidation catalyst for alcohols is a 1-alkyl-2-azadamantan-N-oxyl which has a nitroxyl group incorporated in the adamantane skeleton and was synthesized from as a base material a bicyclic compound obtained by the Grob-type ring-opening reaction of 1,3-adamantanediol. Due to the nitroxyl group on the adamantane skeleton, the α-position hydrogen is stabilized based on Bredt's rule and the stability of the oxoammonium group generated by the oxidation thereof is ensured. Compared to TEMPO, which is a conventional oxidation catalyst, this catalyst is reduced in steric hindrance and is usable in a wide range of reaction fields. Because of this, not only a primary alcohol but a secondary alcohol having a sterically complicated structure, which has been difficult to oxidize with TEMPO, can be oxidized at a high efficiency.
