RUTHENIUM-ALKYLIDENES CONTAINING ACYCLIC DIAMINOCARBENES FOR OBTAINING LOW E/Z RATIOS IN CROSS METATHESIS

摘要

According to one embodiment, the disclosure provides a ruthenium (Ru)-based olefin metathesis reaction catalyst containing a core including a ruthenium-based alkylidene and at least one acyclic diaminocarbene (ADC) ligand covalently bound to the core. The disclosure also provides a method of catalyzing an olefin metathesis reaction by reacting a first olefin and a second olefin in the presence of a ruthenium (Ru)-based olefin metathesis reaction catalyst comprising a core comprising a ruthenium-based alkylidene and at least one acyclic diaminocarbene (ADC) ligand covalently bound to the core to synthesize a third olefin mixture. Finally, the disclosure further provides methods of preparing ruthenium (Ru)-based catalysts.
