Paichongding and Cycloxaprid are two novel neonicotinoids with good industrialization prospects for their high activity against imidacloprid-resistant pest. In this paper, the radiosynthesis of [3H2]-Paichongding and [3H2]-Cycloxaprid was achieved using a NaB3H4 reduction. The title compounds were obtained with chemical purities of 98.7 and 98.4%, and radiochemical purities of 97.3 and 98.6%, respectively. The labeled compounds could be used as radiotracers for further study of metabolism and toxicology. Copyright © 2011 John Wiley & Sons, Ltd. |
