    • Synthetic methods for the in-situ formation of olefin metathesis catalysts are disclosed, as well as the use of such catalysts in metathesis reactions of olefins and olefin compounds. In one aspect, a method is provided for synthesizing an organometallic compound of the formula (I); comprising contacting a precursor compound of the formula (X 1 X 2 ML j L 1 k L 3 m ) i with an acetylenic compound of the formula comprising a chelating moiety, optionally, in the presence of a neutral electron donor, wherein M is a Group 8 transition metal, L, L 1 , L 2 , and L 3 are neutral electron donors, X 1 and X 2 are anionic ligands, j is 1, 2, or 3; k is zero, 1, or 2; m is zero or 1; n is 1 or 2; and i is an integer; with the proviso that k is zero when the precursor compound is contacted with the acetylenic compound in the presence of the neutral electron donor, and R 1 and R 2 are independently selected from hydrocarbyl, substituted hydrocarbyl, heteroatom-containing hydrocarbyl, substituted heteroatom-containing hydrocarbyl, and functional groups, wherein R1 and R2 are linked and together form one or more cyclic groups, R 2 and L 2 are linked and together form one or more cyclic groups, and any other two or more of X 1 , X 2 , L 1 , L 2 , L 3 , R 1 , and R 2 can be taken together to form one or more cyclic groups. The invention has utility in the fields of catalysis, organic synthesis, polymer chemistry, and industrial and fine chemicals chemistry.
