In two earlier publications2 we discussed activation volumes of a number of solvolysis reactions considered by many chemists to proceed at enhanced rates because of neighboring group participation. This activation parameter, the value of which is typically3 of the order of -15 --20 cm3/mole for sol

The kinetic pressure effect on some Michael-like and [4 2] cycloadditions in aqueous solution was studied. This effect is complex and variable, in contrast to the pressure dependence of rate constants in organic solvents. In order to determine the origin of this kinetic behavior, systematic solvent
The activation and reaction volumes (βV /βV) were showing negative volumes of activation (βV Ο½ 0) whereas the others are slightly retarded (βV ΟΎ 0). From the analysis determined for the retro Diels-Alder reactions of the parent dihydrobarrelene 1a, its 2-cyano derivative 1b, the exo and of the volum
