Single-site organometallic catalysts

Isolated Organometallic Catalysts on Silica Supports - Towards Single-Site Solid Catalysts... 

This is a major achievement, mainly due to Basset and his group, in surface organometallic chemistry because it has been thus possible to prepare single site catalysts for various known or new catalytic reactions [53] such as metathesis of olefins [54], polymerization of olefins [55], alkane metathesis [56], coupHng of methane to ethane and hydrogen [57], cleavage of alkanes by methane [58], hydrogenolysis of polyolefins [59] and alkanes [60], direct transformation of ethylene into propylene [61], etc. These topics are considered in detail in subsequent chapters. 

Preparation of Single Site Catalysts on Oxides and Metals Prepared via Surface Organometallic Chemistry... 

If by chance one discovers that the rules of molecular chemistry apply to these surface organometallic fragments then it must be possible to transpose the concepts of modern molecular chemistry to design heterogeneous catalysts and especially the single sites that are necessary to get higher activities, better selec-tivities and higher life times, and eventually to discover new catalytic reactions.
