Greener iodination of arenes using sulphated ceria-zirconia catalysts in polyethylene glycol
Kahandal, S. S., S. R. Kale, M. B. Gawande, R. Zboril, R. S. Varma, AND R. V. Jayaram. Greener iodination of arenes using sulphated ceria-zirconia catalysts in polyethylene glycol. RSC Advances. RSC Publishing, Cambridge, Uk, 4(12):6267-6274, (2014).
An environmentally benign method for the selective monoiodination of diverse aromatic compounds has been developed using reusable sulphated ceria-zirconia under mild conditions. The protocol provides moderate to good yields of aryl iodides in PEG-200 as a greener solvent. The catalyst with composition, SO42-/Ce0.07Zr0.93O2, was found to be excellent to generate the corresponding aryl iodides in high yield presumably due to the total number of acid sites (4.23 mmol g-1), which is quite high comparative to other compositions.
