The utilization of biobased feedstocks to prepare useful compounds is a pivotal trend in current chemical research. Among varied portfolio naturally available starting materials, fatty acids are abundant, versatile substrates with multiple applications. In this context, the ethenolysis unsaturated acid esters such as methyl oleate an atom-economical way functional C10 olefins footprint. Despite existence variety metathesis catalysts for latter process, there lack readily available, efficient, and inexpensive catalytic systems based on earth-abundant metals (Mo, W) whose preparation does not require sophisticated syntheses manipulations. Here, systematic exploration homogeneous heterogeneous inorganic Mo, W (oxy)halides shows that MoOCl4, while inactive species, forms active selective silica-supported precatalysts able reach equilibrium conversion within few minutes upon activation SnMe4. Such MoOCl4-based were easily accessed through mechanochemical solvent-free procedures found contain, characterization by elemental analysis Raman spectroscopy, isolated (≡SiO)Mo(═O)Cl3 units or polymeric [–O(≡SiO)nMoCl4–nO–]m (n = 1, 2) complexes depending molybdenum loading. former species exhibited higher performance. developed could be applied various substrates, including polyunsaturated industrial ester (FAME) mixtures from palm oil transesterification.
