METHODS FOR PREPARING RUTHENIUM CARBENE COMPLEX PRECURSORS AND RUTHENIUM CARBENE COMPLEXES

摘要

A method for preparing a ruthenium carbene complex precursor includes reacting a ruthenium refinery salt with a hydrogen halide to form a ruthenium intermediate, and reacting the ruthenium intermediate with an L-type ligand to form the ruthenium carbene complex precursor. A method for preparing a ruthenium vinylcarbene complex includes converting a ruthenium carbene complex precursor into a ruthenium hydrido halide complex, and reacting the ruthenium hydrido halide complex with a propargyl halide to form the ruthenium vinylcarbene complex. A method for preparing a ruthenium carbene complex includes converting a ruthenium carbene complex precursor into a ruthenium carbene complex having a structure (PR1R2R3)2Cl2Ru═CH—R4, wherein R1, R2, R3, and R4 are alike or different, and wherein covalent bonds may optionally exist between two or more of R1, R2, and R3.

1. A method of preparing a MX2Lq complex comprising:
reacting a ruthenium (IV) hexahalo complex that comprises a [RuX1yX26-y]2− anion with an L-type ligand to form a MX2Lq complex; wherein M is ruthenium; wherein X1 and X2 are halogen atoms that are independently selected from the group consisting of Cl and Br; wherein y is an integer value from 1 to 6; and wherein q is 3.
