of a photomediator such as benzophenone, alkynes with electron-withdrawing groups react with cycloalkanes to give vinyl cycloalkanes. The reaction involves the regiospecific addition of a photochemically generated cycloalkyl radical to the beta-carbon of the alkyne. The stereochemical outcome of the reaction depends on the nature of the photomediator and alkyne used.
在光介体如二苯甲酮的存在下,具有吸电子基团的炔烃与环烷烃反应生成乙烯基环烷烃。该反应涉及将光化学产生的环烷基的区域特异性加成到炔烃的β-碳上。反应的立体化学结果取决于所使用的光介体和炔烃的性质。
