Selective n π* excitation of the α,β-unsaturated enone 1 in hydrocarbon solvents resulted in a deconjugation reaction to 3, reminiscent of results previously reported for similar systems [2], whereas the photoreactivity of 1 in alcohol solvents at wavelengths >3400 Å was so small that only product 4 has been identified as yet.
选择性Ñ π*的α的激励,β不饱和烯酮1在烃溶剂中产生了去缀合反应3,使人联想起先前针对相似的系统[2]报道的结果,而的光反应性1在醇溶剂中在波长> 3400埃太小了,以至于只识别出了产品4。
