Abstract

Abstract: The Pauson-Khand cobalt-mediated cycloaddition has become a synthetically important reaction. Several modifications have increased the utility of the reaction, including reports that tertiary amine N-oxides greatly accelerate the rate of cycloaddition in both intra- and some intermolecular reactions. To date, there has been no direct evidence to support the mechanistic hypotheses for either the thermal or amine oxide promoted reactions ...
