Catalysis action is usually held to be preceeded by some form of chemical interaction of one reactant, or of both, with the catalyst. Toluene has certain distinctive features from this point of view. The carbon-hydrogen bond dissociation energy for the side chain bonds is about 84kcal. Mol −1 while the ring carbon-hydrogen bond energy is probably greater than 103 kcal. Mole−1.1 The side chain gives aliphatic characteristics while the aromatic ring of toluene adds the further possibility of interaction with the catalyst through its unsaturated properties and, as a special aromatic feature, through the T-ring system. It was the possible interplay of these features which suggested this research. The brief literature survey deals with general features of the exchange reactions of maturated hydrocarbons, unsaturated and aromatic compounds only in so far as the main features are judged to have a bearing on the toluene problem and to show the development of features common to most exchange reactions. The catalyst metal was varied in the experimental part of this work and since this can be viewed as altering the nature of toluene's reaction partner some relevant similar work in the literature is summarised. Evaporated films of metal were chosen as catalytic agents in order to avoid possible complications arising from supporting materials and differing preparatory methods from metal to metal. Wherever possible work on metal film catalysts will therefore be used to provide the examples is the following literature survey.
