- Palladium-catalyzed intramolecular arylation of N-benzyl-2-iodoimidazoles: A facile and rapid access to 5H-imidazo[2,1-α]isoindoles
-
The first example of a Pd-catalyzed intramolecular arylation involving the C-2 position of an imidazole ring is presented. Application of this reaction led to the formation of 5H-imidazo[2,1-a]isoindole in one step from N-benzyl-2-iodoimidazole. Microwave irradiation enhanced the rate of reaction allowing the synthesis of various imidazo[2,1-a]isoindole analogues. Georg Thieme Verlag Stuttgart.

- A comparison of microwave-accelerated and conventionally heated iodination reactions of some arenes and heteroarenes, using ortho-periodic acid as the oxidant
-
A fast and simple method for the oxidative iodination of some activated arenes and heteroarenes, either under microwave irradiation or by conventional heating, is reported, using diiodine and ortho-periodic acid as the oxidant. The reactions were carried out in hot 95% ethanol under a reflux condenser. For the microwave assisted reactions, the reaction times were always notably shortened, but the yields were nearly the same as those afforded by the conventional method.
