Abstract

Novel site-isolated tetracoordinated molybdenum complexes possessing bis(imido) ligands, [( - Si-O)₂Mo( - NR)₂] (R = t-Bu, 2,6-C₆H₃-i-Pr₂), were immobilized on partially dehydroxylated silica (SiO_2-200) by a rigorous surface organometallic chemistry protocol. The newly developed materials adorned with bis(imido) functional units, which were previously exploited mainly as spectator ligands on silica-supported olefin metathesis molybdenum catalysts, are found to be efficient heterogeneous catalytic systems for imine cross metathesis under mild conditions.
