2, Na+ was investigated by a flow and a stopflow technique. The bimolecular rate constant of combination was found to be 2 to 3 x 106 1. mole-1 s-1. The reaction was initiated by an electron transfer naphthalene^ + (P/*,2C:CH2) naphthalene+ (P/*,2C:CH^) or terphenylener + (P7fc2C:CH2) ⇔ terphenylene + (Pfe2C:CH^). The equilibrium constant of the first electron transfer process was found to be 20 and of the second about 16. These results are consistent with recent determinations of electron affinities of aromatic hydrocarbons.
