Solvolysis of (<i>Z</i>)- and (<i>E</i>)-2-Ethylidene-1-adamantyl Chlorides and Mesylates. A Unique Example Showing the Greater F-Strain Effect in the Chloride than in the Mesylate
The Z/Erate ratio in the trifluoroethanolysis at 25 °C of the title chlorides and mesylates are 1023 and 126, respectively, showing the greater front strain (F-strain) effect in the (Z)-chloride than in the (Z)-mesylate. The results were supported by MM2 and AM1 calculations.
