Abstract: To assess the magnitude and direction of equilibrium caused by certain electronegative atoms, three 2, 8-annulated semibullvalenes have been synthesized. These molecules are directly patterned in structure after the 2.8-trimethylene bridged hydrocarbon which was known to exhibit approximately equal partiality for the two valence tautomeric forms at room temperature. For the three cases where the central methylene group was ...
