The relative ratio of enone-CPD adducts and C15H18 formed in the photochemical reaction between cyclohex-2-en-1-one and its 4,4 dimethyl derivative and CPD in different media suggest that an exciplex is responsible for 2+2 photoannelation and energy transfer and a transoid or twisted enone for photo Diels-Alder reaction.
环己-2-烯-1-酮及其4,4二甲基衍生物与CPD在不同介质中的光化学反应中形成的烯酮-CPD加合物和C 15 H 18的相对比例表明,激基复合物是2 + 2的原因。光退火和能量转移,以及用于光Diels-Alder反应的透明或扭曲的烯酮。
