This invention relates generally to C—H activated ruthenium olefin metathesis catalyst compounds which are stereogenic at the ruthenium center, to their preparation, and the use of such catalysts in the metathesis of olefins and olefin compounds. In particular, the invention relates to the use of C—H activated ruthenium olefin metathesis catalyst compounds in Z-selective olefin metathesis reactions, enantio-selective olefin metathesis reactions, and enantio-Z-selective olefin metathesis reactions. The invention has utility in the fields of catalysis, organic synthesis, polymer chemistry, and industrial and fine chemicals chemistry.

Cis and trans ruthenium complexes that can be used as catalysts for ring opening metathesis polymerisation (ROMP) are described. The complexes are generally square pyramidal in nature, having two anionic ligands X. Corresponding cationic complexes where one or both of the anionic ligands X are replaced by a non-co-ordinating anionic ligand are also described. Polymers such as polydicyclopentadiene (PDCPD) can be prepared using the catalysts.
used as sustainable acyldonors for enzymatic acylation of chiral and nonchiral alcohols. Especially, it was revealed that geminal diacetates showed higher reactivity than vinyl acetate for hydrolases that are sensitive to acetaldehyde. Under optimized conditions for enzymatic acylation, several synthetically relevant saturated and unsaturated acetates of various primary alcohols were obtained in very
