Radical-anion intermediates. Part 8. The influence of a crown ether on the fluorene and 9-methylfluorene radical-anions
Abstract
The addition of dibenzo-18-crown-6 has been found to influence the rate of decay of the fluorene and 9-methyl-fluorene radical anions. The influence is most significant when Li+ is the counterion and the second-order kinetics observed with this counterion in the absence of the crown ether have been found to be prevented by its addition.
