Abstract Grafting Ti(=N t Bu)(Me 2 Pyr) (py) (Me Pyr= 2,5‐dimethylpyrrolyl, py=pyridine) onto the surface of silica partially dehydroxylated at 700 °C gives well‐defined silica‐supported Ti imido complex (≡SiO)Ti(=N Pyr)(py) , which is fully characterized by IR and solid‐state NMR spectroscopy as well elemental mass balance analyses. While stoichiometric imido‐transfer reactivity typical for imides, obtained unique in that it enables catalytic transformations involving oxo intermediates. In...

We expand the series of well-defined silica-supported titanium imido complexes general formula (≡SiO)Ti(═NtBu)X(py)n prepared via surface organometallic chemistry in order to analyze effect X ligand on their catalytic properties. Two new complexes, (≡SiO)Ti(═NtBu)Cl(py)2 (2s) and (≡SiO)Ti(═NtBu)Cp(py) (3s), have been characterized with physicochemical techniques, performance oxo/imido heterometathesis other imido-transfer reactions has studied compared that previously reported catalyst...

Abstract A Surface OrganoMetallic Chemistry (SOMC) approach is used to prepare a novel hafnium‐iridium catalyst immobilized on silica, HfIr/SiO 2 , featuring well‐defined [≡SiOHf(CH t Bu) (μ‐H) 3 IrCp*] surface sites. Unlike the monometallic analogous materials Hf/SiO and Ir/SiO which promote n ‐pentane deuterogenolysis through C−C bond scission, we demonstrate that under same experimental conditions (1 bar D 250 °C, h, 0.5 mol %), heterobimetallic highly efficient selective for...
