为了使二苯乙烯光环化，在不存在空气的情况下化学计量量的碘加环氧丙烷上级在空气中催化量的碘。环氧丙烷防止HI光还原双键。空气的不存在防止了光氧化副反应，在一种情况下显示出由光生氧化剂（可能是过氧化氢）引起。
To photocyclize stilbenes, a stoichiometric amount of iodine plus propylene oxide in the absence of air is superior to a catalytic amount of iodine in the air. The propylene oxide prevents HI from photoreducing double bonds. The absence of air prevents photooxidative side reactions, shown in one case to be caused by a photogenerated oxidant, possibly hydrogen peroxide.
