tandem platinum dichloride‐catalyzedcycloisomerization 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‐catalyzedcycloisomerization products, bicyclo[4.1.0]hept‐2‐enes, undergo a Claisen rearrangement, a 1,5‐hydrogen
