Free radical addition of t-BuHgI/KI to 1-vinyl-4-pentenyl acrylates in DMSO followed by a photostimulated reaction with Ph2S2 leads to the formation of free radical cyclization products 3 by the 8-endo mode and/or 5 by the 5-exo mode.
在DMSO中将t-BuHgI / KI自由基加成到1乙烯基-4-戊烯基丙烯酸酯中,然后与Ph 2 S 2光刺激反应,导致通过8内基模式和/或5形成自由基环化产物3通过5 exo模式。
