The formation and the lifetimes of several aromatic anions in irradiated solutions of arenes in the aliphatic alcohols have been investigated by the pulse radiolysis technique. The aromatic anions show a fast decay which follows a firsthyphen;order rate law. The absolute rate constants for this decay, suggested to be a proton transfer from the alcohol,areneminus;plus;ROHequals;arene Hmiddot;plus;ROminus;,have been determined for four alcohols and three aromatic anions. The rate constants, which are found to be in the orderCH3OHC2H5OHcong;C3H7OHlpar;CH3rpar;2CHOH, show a close correlation with other measurements of the acidity of the alcohols.The absolute rate constants have also been determined for the reaction of several aromatic anions with hydrogen ion,areneminus;plus;ROH2plus;equals;arene Hmiddot;plus;ROH,and for the attachment reaction of the solvated electron in ethanol,esolminus;plus;areneequals;areneminus;.
