tandem platinum dichloride‐catalyzed cycloisomerization and rearrangement reaction of enynes leads to the formation of 2,4‐pentadienals, 1‐aryl‐tetrahydro‐1H‐indenes, or 3‐methylene‐4‐vinylcyclohex‐1‐enes; depending upon the substituent(s) and tether group of the enynes, the platinum dichloride‐catalyzed cycloisomerization products, bicyclo[4.1.0]hept‐2‐enes, undergo a Claisen rearrangement, a 1,5‐hydrogen
乙炔的串联二氯化铂催化的环异构化和重排反应导致形成2,4-戊二烯醛,1-芳基-四氢-1 H-茚或3-亚甲基-4-乙烯基环己烯-1-烯; 根据烯炔的取代基和系链基团,二氯化铂催化的环异构化产物双环[4.1.0]庚-2-烯经历克莱森重排,1,5-氢位移或乙烯基环丙烷重排。
