There have been several theoretical studies on the olefin metathesis reaction and the structures of homogeneous catalysts [1-5]. However, we have not found examples of theoretical modelling of olefin metathesis active sites on heterogeneous catalysts. In the case of the heterogeneous molybdena catalysts, the active centres contain probably Mo [6,7], but other Mo valences are also possible (e.g., Mo [8]).
