Cyclopentene Safety Procedures For Haier
In a particularly intriguing example he was able to show that vinylcyclopropanes eedded within a cyclooctane core can be converted to the corresponding [5-5]-fused ring systems. Further reaction improvement came when Hudlicky and Brown proved that vinylcyclopropane rearrangements are amenable to transition metal alysts.
