詳細

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.

アプリケーション

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

A method to oxidatively cleave allyl ethers to their corresponding aldehydes mediated by an oxoammonium salt is described. Using a biphasic solvent system and mild heating, cleavage proceeds readily, furnishing a variety of α,β-unsaturated aldehydes and ketones.

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

Dr. James Bobbitt has been developing the chemistry of oxoammonium salts, such as Bobbitt's Salt (Product 745537), for 30 years. He discovered the oxoaommonium chemistry by accident in 1985 and found that it had been started by a fine Russian chemist called Valery Golubev. At the University of Connecticut, he has had major collaborations with Professor Christian Bruckner, Professor William Bailey, and Professor Nicholas Leadbeater. He does most of his own experimental work, much of which has been published. Even though he is into his mid-80's, he continues to work on several chemistry projects as an Emeritus Professor at UConn.
