Organometallic compounds, including metal clusters, grafted on the surface of supports have been widely used as catalyst precursors to provide a rational approach for the preparation of tailored metal catalysts.1 It is known that ethene metathesis proceeds on both homogeneous and heterogeneous Mo catalysts,2 while ethene homologation takes place on hetero- geneous Mo catalysts.3 Ethene dimerization has only been reported to occur when monomer Mo ...
