wavelength dependent product selectivity observed upon irradiation of a substituted 2,5-cyclohexadien-1-one is shown to result from wavelength dependent quantum yields for rearrangement of the primary photoproduct bicyclo[3.1.0]hexenones. Reaction selectivity can be optimized by careful choice of irradiation wavelength and length of irradiation time.
辐照取代的2,5-环
己二烯-1时观察到的与波长无关的产物选择性异常,显示是由对初级光产物双环[3.1.0]六氢
壬烯的重排与波长有关的量子产率引起的。可以通过仔细选择照射波长和照射时间长度来优化反应选择性。
