Solid/liquid phase-transfer catalysis. Some models and solvent influence

The applicability of the models developed earlier for the topochemical reactions in the solid/liquid phase-transfer catalysis is discussed. Depending on the solvent and the catalyst the reaction may be inhibited by the crust of the solid inorganic product. Solvents like MeCN and THF, and catalysts such as polyethylene glycols loosen this crust, thus preventing the inhibition. The solvent influence using the E(T)(30) parameter in different reactions in the solid/liquid system is investigated.
