Abstract
The photochemical [2+2] cycloaddition of beta,beta-dimethyl-p-methoxystyren e to C-60 occurs With loss of stereochemical integrity. The substantial rem ote kinetic isotope effect in the title reaction, indicates the formation o f an open, relatively long lived intermediate. (C) 2000 Published by Elsevi er Science Ltd.
