Preparation of 9‐Azabicyclo[3.3.1]nonane‐N‐Oxyl (ABNO)

Abstract

Abstract This chapter describes the procedure for preparation of 9‐azabicyclo[3.3.1]nonane‐N‐oxyl (ABNO). ABNO is an effective catalyst for aerobic oxidation of alcohols to ketones and aldehydes. This type of oxidation is particularly attractive for large scale preparations because of the potential to reduce cost and minimize waste. The chapter presents some of the important points to be considered, the conditions that need to be maintained, characterization data, and the reagents required, as well as the techniques used and the equipment setup that are vital to carrying out the process. It also describes the hazards associated with working with chemicals and the ways to deal with these hazards.
