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.

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.
