TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: In the process (B), the triacylglyceride is contacted with alcohol and converted to a fatty acid ester or fatty acid alkyl ester prior to contacting with the catalyst compound (I); or the triacylglyceride is contacted with water or an alkaline reagent and converted to a fatty acid prior to contacting with the catalyst compound (I). Preferred Components: The feed oil is selected from canola oil, corn oil, soybean oil, rapeseed oil, algae oil, peanut oil, mustard oil, sunflower oil, tung oil, perilla oil, grape seed oil, linseed oil, safflower oil, pumpkin oil, palm oil, Jathropa oil, high-oleic soybean oil, high-oleic safflower oil, high-oleic sunflower oil, mixtures of animal and vegetable fats and oils, castor bean oil, dehydrated castor bean oil, cucumber oil, poppy seed oil, flaxseed oil, lesquerella oil, walnut oil, cottonseed oil, meadow foam, tuna oil, and/or sesame oils (preferably palm oil, or algae oil). The unsaturated fatty acid ester of process (C) is a fatty acid methyl ester. For process (C) that utilizes a triacylglyceride, fatty acid, fatty acid alkyl ester, and/or fatty acid ester derived from seed oil, the alkene is selected from ethylene, propylene, butene, pentene, hexene, heptene, octene, and/or nonene (preferably ethylene), the alpha olefin is 1-butene, 1-heptene and/or 1-decene; and the feed material is a fatty acid methyl ester and/or fatty acid ester. Preparation (disclosed): The preparation of metathesis catalyst compound (I) involves: treating a solution of indenylene ligand complex in a solvent (e.g. tetrahydrofuran (THF)) with a reactant complex of Group 8 metal (e.g. dichloro-bis-(triphenylphosphine)ruthenium (II)), and acetyl chloride; heating the mixture to reflux for a time to yield the chelating indenylene catalyst compound; and optionally adding a phosphine ligand (e.g. tricyclohexylphosphine) in solvent (e.g. benzene), and reacting for a time to effectuate phosphine ligand exchange; adding copper(I) chloride in excess and removing volatiles from resultant slurry to afford the Group 8 chelating indenylene catalyst compound comprising the more preferred phosphine ligand. Preferred Definitions:    M'=Ru;    X and X1=Cl;    L'=phosphine, N-heterocyclic carbene, or cyclic alkyl amino carbine;or    L'+X=multidentate monoanionic or dianionic group, or multidentate monoanionic or dianionic group which forms single ring of up to 30 non-hydrogen atoms or multinuclear ring system of up to 30 non-hydrogen atoms;    L1=N, or O;    G1=H, or optionally substituted alkyl;    G'=1-30C optionally substituted alkyl, or 4-30C optionally substituted aryl;    R1=phenyl substituted by methoxy.    SPECIFIC COMPOUNDS - 3 Compounds i.e. triphenylphosphinedichlorideruthenium(3-(3,5-dimethoxyphenyl)-6,8-dimethoxyinden-1-ylidene) of formula (Ia); triphenylphosphinedichlorideruthenium(3-pentafluorophenyl-6,8-diisopropoxyinden-1-ylidene); and tricyclohexylphosphinedichlorideruthenium (3-pentafluorophenyl-6,8-diisopropoxyinden-1-ylidene); are specifically claimed as the metathesis catalyst compound (I).    EXAMPLE - Acetyl chloride (5-10 mu l) was added to a solution of (PPh3)3RuCl2 (336 mg) and 1,1-bis(3,5-dimethoxyphenyl)prop-2-yn-1-ol (172 mg) in tetrahydrofuran (THF) (6 ml). The propynol was added as a 0.2 M solution in THF. The solution was allowed to reflux for 18 hours, after which the reaction flask was placed under high vacuum to remove the solvent. Isopropanol (12 ml) was added to the reaction flask and the purple material was removed from walls by intense stirring overnight. The resulting suspension was filtered and washed with isopropanol (5 ml) followed by two pentane washes (5 ml each). Any remaining solvent was removed from the red-brown powder in vacuum at 60 degrees C, yielding triphenylphosphinedichlorideruthenium(3-(3,5-dimethoxyphenyl)-6,8-dimethoxyinden-1-ylidene) (240 mg; 92%).
