The present invention relates to a process for driving a non-polymerization solution-phase photochemical transformation. A sensitizer, such as a substituted diaminobenzophenone having a solubility in norbornadiene greater than that of Michler's Ketone, may be added to norbornadiene to form a solution, wherein the sensitizer decreases the induction period at the beginning of the reaction, increases the photon or quantum efficiency of conversion of norbornadiene to quadricyclane, and increases the rate of conversion at the end of the reaction. If the solution is irradiated with light from a metal halide-doped mercury arc lamp to photochemically transform the norbornadiene to quadricyclane, the conversion is more efficient than when other light sources are utilized. Furthermore, the addition of triethylamine to the solution tends to result in the formation of fewer by-products in the transformation reaction.
