The use of bromotrichloromethane-DBU is described for the selective oxidative conversion of several dihydro-heterocyclic systems to the corresponding heteroaromatics. Oxidative dehydrogenations to afford 4hydroxy-2-pyridinones are examined under a variety of conditions. Studies of phenylselenenylati
## Abstract The kinetics of thallation of fluorene with thallium triacetate (TTA) in HOAcβH~2~SO~4~ solutions led to the rate expression The rate of thallation is found to increase with increasing acid concentration, and a sixthβorder dependence on [H~2~SO~4~] is observed. Decrease in solvent pol
