Abstract
The combination of triflic anhydride and 2.6-di-tert-butyl-4-methylpyridine was found to be a selective reagent system For the conversion of cyclic 1, 3-diones to the corresponding monotriflate derivatives, The use of N-(5-chl oro-2-pyridyl)triflimide together with KHMDS was selective for the preparat ion of the corresponding ditriflates. The Suzuki coupling reactivity of bot h the mono- and ditriflates was also explored. (C) 2001 Elsevier Science Lt d. All rights reserved.
