Carbon Acidity. 59. First and Second Ion-Pair Acidity Constants for 9,10-Dihydroanthracene with Cesium Cyclohexylamide1 Sir:Although dimetalated and even more highly metalated hydrocarbons are not uncommon,2 no equilibrium constants for such higher metalations have previously been measured. We report here both the first and second acidity constants for 9,10-dihydroanthracene (DHA) expressed as pXcsCHA values in the cesium cyclohexylamide (CsCHA)-cyclohexylamine (CHA) system.3The procedure for measuring the spectra of the cesium salts was essentially that used previously,4 and the relevant data are summarized in Table I. Commercially obtained DHA was purified by recrystallization from ethanol followed by vacuum
