Abstract

Phosphorus changes stability: Investigation of the phosphorus polycycles 1 and 2, prepared according to Equation (1), show that the relative stability of the norbornadiene and quadricyclane frameworks is inverted when four of the framework carbon atoms are replaced by phosphorus atoms. These organophosphorus compounds can be isolated at room temperature but are in equilibrium at elevated temperatures. The experimental findings are in agreement with the results of ab initio MO theory calculations.
