Mononuclear platinum complexes often have been used as models for catalytic intermediates since systematic studies of synthesis, reactivity, and mechanism are often convenient and because metallic platinum is a very important catalyst. However, using binuclear or polynuclear platinum complexes as models for proposed intermediates in heterogeneous catalysis has not been studied, probably because planned routes to such complexes have not been available. This chapter describes our first studies in this area. 

The nature of intermediates in heterogeneous catalysis by acid form zeolites attracted considerable interest since the first experiments by Derouane et al. on characterization of adsorbed hydrocarbons with CP/MAS NMR [14]. Alkyl carbenium ions, which were...
