Eight fluorinated compounds were tested as putative probes to measure carboxylesterase activity employing 19F nuclear magnetic resonance spectroscopy. The method takes advantage of the sensitivity of fluorine resonances to the changes in the chemical bonding in the covalent structures where

Palladium-catalyzed reactions of aryl bromides and chlorides with two common stabilized carbanions-enolates of dialkyl malonates and alkyl cyanoesters-are reported. An exploration of the scope of these reactions was conducted, and the processes were shown to occur in a general fashion.
