Abstract

Abstract: The thermolyses of a series of 1, 4-bridged bicyclo [2.2. 0] hexanes have been studied. With bridges having three or more carbons, the compounds have higher activation energies than for bicyclo [2.2. 0] hexane, indicating that the bridge prevents the formation of a chair cyclohexane-l, 4-diyl, forcing the reaction to proceed via an orbital symmetry disallowed process. It appears likely that [2.2. 2] propellane and its derivatives react via ...
