C-Alkylation is an important class of synthetic reaction employed in the fine chemical industry. Although a number of C-alkylation reactions are reported under liquid-liquid (LL) phase transfer catalysis (PTC) leading to intensification of reaction rates, there is a dearth of information on similar reactions under the solid-liquid (SL) PTC including kinetics and mechanism. SL PTC offers higher rates of reaction and better selectivities to the desired ...
