Uses

Used in Food Preservation Industry:
9-Eicosene is used as a natural preservative for processed foods to inhibit the growth of common bacteria that cause spoilage and reduce the shelf-life of these products. Its natural antibacterial properties make it a valuable addition to the food industry for maintaining the quality and safety of processed foods.

The synthesis of W(NAr′)(NHC)(=CHR)(2,5-Me2pyr)2 (1; Ar′: 2,6-iPr2C6H3; NHC: 1,3-diisopropylimidazol-2-ylidene; 2,5-Me2pyr: 2,5-dimethylpyrrolide; R: CMe2Ph), W(NAr′)(NHC)(=CHR)(2,5-Me2pyr)(OC6F5) (2), W(NAr′)(NHC)(=CHR)(OSiPh3)2 (3), [W(NAr′)(NHC)(=CHR)(OSiPh3))(MeCN)+][B(ArF)4 ?] (4; B(ArF)4 ?: B(3,5-(CF3)2C6H3)4 ?), [W(NAr′)(NHC)(=CHR)(2,5-Me2pyr))+][B(ArF)4 ?] (5), [W(NAr′)(NHC)(=CHR)(OC6F5))(tBuCN)+][B(ArF)4 ?] (6), W(NAr′)(NHC)(=CHR)(OtBu)2 (7), [W(NAr′)(NHC)(=CHR)(OtBu)+][B(ArF)4 ?] (8), and W(NAr′)(NHC)(=CHR)(OCMe(CF3)2)2 (9) is described, and the reactivity of the complexes in olefin metathesis and cyclopolymerization is reported. The cationic complexes 4, 5, and 6 showed high productivity and activity in olefin metathesis reactions, with turnover numbers of up to 40 000 and turnover frequencies (TOF5min) of up to 31 s?1, and also substantial functional group tolerance toward esters, nitriles, alcohols, and sulfides, particularly in the cyclopolymerization of α,ω-diynes.

Method of producing dicarboxylic acids

A method of producing dicarboxylic acids (e.g., α,ω dicarboxylic acids) by reacting a compound having a terminal COOH (e.g., unsaturated fatty acid such as oleic acid) and containing at least one carbon-carbon double bond with a second generation Grubbs catalyst in the absence of solvent to produce dicarboxylic acids. The method is conducted in an inert atmosphere (e.g., argon, nitrogen). The process also works well with mixed unsaturated fatty acids obtained from soybean, rapeseed, tall, and linseed oils.
