Patent number: 11779911Abstract: In one aspect, the invention provides a method for synthesizing a fatty olefin derivative. The method includes: a) contacting an olefin according to Formula I with a metathesis reaction partner according to Formula IIb in the presence of a metathesis catalyst under conditions sufficient to form a metathesis product according to Formula IIIb: and b) converting the metathesis product to the fatty olefin derivative. Each R1 is independently selected from H, C1-18 alkyl, and C2-18 alkenyl; R2b is C1-8 alkyl; subscript y is an integer ranging from 0 to 17; and subscript z is an integer ranging from 0 to 17. In certain embodiments, the metathesis catalyst is a tungsten catalyst or a molybdenum catalyst. In various embodiments, the fatty olefin derivative is a pheromone. Pheromone compositions and methods of using them are also described.Type: GrantFiled: July 30, 2021Date of Patent: October 10, 2023Assignee: PROVIVI, INC.Inventors: Keith M. Wampler, Peter Meinhold, Pedro Coelho, Vu Bui, Hasan Mehdi

Publication number: 20220227797Abstract: The invention relates to tungsten imido alkylidene compounds bearing a ligand derived from a 1,1?-binaphthyl-2-ol or a 5,5?,6,6?,7,7?,8,8?-octahydro-1,1?-binaphthyl-2-ol which bind to tungsten in its olate-form via proton abstraction from the phenolic OH group. The complexes may be used in various olefinic metathesis reactions, preferably ethenolysis and cross-metathesis of unsaturated fatty acid esters, and ring-closing metathesis reactions.Type: ApplicationFiled: May 27, 2020Publication date: July 21, 2022Inventors: Levente Ondi, Csaba Hegedüs, Ágota Bucsai, Jeno Varga, Benedek Vakulya, Krisztian Lorincz, Henrik Gulyas, Hasan Mehdi
