methods for the preparation of ruthenium and carbene complex precursors and ruthenium and carbene complexes

摘要

Patent Application: "Methods for the preparation of precursors of ruthenium and carbene complexes and ruthenium and carbene complexes". The present invention relates to a method for the preparation of a ruthenium carbene complex precursor which includes the reaction of a ruthenium refining salt with a hydrogen halide to form a ruthenium intermediate, and the reaction of ruthenium intermediate with a type 1 ligand to form the precursor of the ruthenium and carbene complex. One method for the preparation of a ruthenium vinyl carbene complex includes the conversion of a ruthenium carbene complex precursor into a hybrid ruthenium halide complex, and the reaction of the hybrid ruthenium halide complex with a propargyl halide to form the ruthenium and carbene complex. A method for the preparation of a ruthenium and carbene complex includes the conversion of a ruthenium and carbene complex precursor to a complex ruthenium and carbene complex that has a structure (pr1r2r3) 2cl2ru = ch-r4, where r1, r2 R 3 and R 4 are similar or different, and wherein covalent bonds may optionally exist between two or more of R 1, R 2 and R 3 and / or two of R 1, R 2 and R 3 taken together may optionally form a phosphorus ring. 21025530v1
