Abstract
The blue species obtained when 1,1-diphenylethylene chemisorbs on highly ac idic solids arises from a very minor dimerization reaction where a less sta ble canonical form of the initial carbenium ion adds to Phi(2)C=CH2 (Phi = phenyl). Proton loss followed by H- ion abstraction from the resulting olef in then affords a highly conjugated ion as the blue species.
