Influence of packing of the reactants and products in solution on the volume parameters of the diels-alder reaction

Abstract

The possible causes of a dramatic difference in the volume parameters (by up to 15-20 cm3 mol-1) of the Diels-Alder reactions involving bulky and small reactants are discussed. The partial molar volumes of anthracene and 9,10-dihydroanthracene and the heats of their solution in six solvents were determined. ©2004 MAIK "Nauka/Interperiodica".
