Catalytic Imido-Transfer Reactions of Well-Defined Silica-Supported Titanium Imido Complexes Prepared via Surface Organometallic Chemistry
We expand the series of well-defined silica-supported titanium imido complexes of general formula (SiO)Ti(NtBu)X(py) n prepared via surface organometallic chemistry in order to analyze the effect of the X ligand on their catalytic properties. Two new surface complexes, (SiO)Ti(NtBu)Cl(py...

Summary: | We expand the series of well-defined silica-supported titanium imido complexes of general formula (SiO)Ti(NtBu)X(py) n prepared via surface organometallic chemistry in order to analyze the effect of the X ligand on their catalytic properties. Two new surface complexes, (SiO)Ti(NtBu)Cl(py)2 (2s) and (SiO)Ti(NtBu)Cp(py) (3s), have been prepared and characterized with physicochemical techniques, and their performance in oxo/imido heterometathesis and other catalytic imido-transfer reactions has been studied and compared to that of the previously reported catalyst (SiO)Ti(NtBu)(Me2Pyr)(py)2 (1s; Me2Pyr = 2,5-dimethylpyrrolyl). |
