1.2.3- Triphenylallyl anions

Such equilibrium constants, Veq. are known only for highly conjugated carbanions, such as in cyclopentadienyl anion in water or triphenylallyl anion in DMSO3. Some values are known for equilibrium constants and enthalpies of equation 1 in the gas phase. Additional energies are available for many compounds by computation—with modern methods, computed energies for equation 2 are reliable to a few kcalmol-1. 

The cyclopropyl-allyl anion case itself turned out to be more of a problem. Mulvaney and Savage reacted the rruns,rruns-l,2,3-triphenylcyclopropane (316) with n-butyllithium/TMEDA which led to one (or more) of the isomeric 1,2,3-triphenylallyl anions (317).
