The mechanism of photo-substitution of ferrocene in haloalkane–ethanol solutions was investigated by the flash photolysis technique and other chemical methods mainly on the ferrocene–carbon tetrachloride–ethanol system. The photoreaction is initiated by the excitation of charge transfer state (electron ...
