Kinetic studies of isoprene cyclodimerization show that the accelerating effect caused by LPDE (solution of lithium perchlorate in diethyl ether) in some organic reactions cannot be ascribed to internal pressure of LPDE. The kinetic effect is essentially due to catalysis through Li+. Additional arguments are provided by comparison of yields obtained in LPDE (0,1 MPa) and in organic solvents (under
