일반 설명

Bobbitt′s salt (oxoammonium salt) is a commonly used oxidizing agent in organic synthesis for the preparation of useful chemical intermediates. This reagent is highly stable to both air and moisture.

애플리케이션

Bobbitt′s salt (4-NHAc-TEMPO+ BF4 −) can be used as a reagent in:       
  • Oxidation of alcohols to their concomitant aldehyde, ketone or carboxylic acid.      
  • Conversion of aldehydes to hexafluoroisopropyl (HFIP) esters via oxidative esterification.,·        
  • Deprotection of allyl ethers to corresponding aldehydes.
  •  Preparation of α,β-unsaturated ketones by dehydrogenation of perfluoroalkyl ketones.

A simple, high yielding, rapid route for the oxidative esterification of a wide range aldehydes to hexafluoroisopropyl (HFIP) esters using the oxoammonium salt 4-acetylamino-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate (1a) is reported. These esters can be readily transformed into a variety of other functional

We describe the synthesis of the lesser-known stoichiometric oxidation reagent 4-acetamido-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate (1, Bobbitt's salt), as well as of 4-acetamido-(2,2,6,6-tetramethyl-piperidin-1-yl)oxyl (2, AcNH-TEMPO). Several representative oxidation reactions are also presented to demonstrate the salt's oxidative capabilities. Bobbitt's salt has a range
