标题 :Synthesis of terminal alkenes from internal alkenes via olefin metathesis
发明人：SCHRODI YANN; PEDERSON RICHARD L; KAIDO HIROKI; TUPY MICHAEL J
权利人:ELEVANCE RENEWABLE SCIENCES
摘要:This disclosure relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by an olefin metathesis catalyst. According to one aspect, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting, in the presence of a ruthenium alkylidene metathesis catalyst, an olefinic substrate comprised of at least one internal olefin with a cross metathesis partner comprised of an alpha olefinic reactant, under reaction conditions effective to allow cross-metathesis to occur, wherein the reaction conditions include a reaction temperature of at least 35° C. The methods, compositions, reactions and reaction systems herein disclosed have utility in the fields of catalysis, organic synthesis, and industrial chemistry.

摘要:The invention relates to a method for the synthesis of pheromones functionalised on one of the ends thereof and comprising at least two conjugated double bonds with a majority stereochemical configuration (E, Z). The reaction is carried out in two steps, comprising: (a) a metathesis reaction between a functionalised olefin and an unsaturated aldehyde, in the presence of at least one specific catalyst selected from the ruthenium complexes comprising a 1,3-diaryl-imidazolidin-2-yl ligand and a styrenyl ether ligand, and (b) the reaction of the product obtained in this way with a triphenylalkylphosphonium salt.

摘要:α,β-Unsaturated aldehydes are useful products as such in agrochemistry, but also potential intermediates for the preparation of important insect pheromones and kairomones. Until now, primarily the thermodynamically more stable (E)-α,β-unsaturated aldehydes have been identified as useful intermediates in the production of conjugated diene pheromone compounds, however, their practical and cost-effective synthesis on an industrial scale remains challenging. The problem to be solved by the present invention is to provide a method for selective oxidation of alkenes to α,β-unsaturated carbonyls which can be further transformed into pheromones and kairomones preferably without isolation and significant loss of the existing stereochemical purity.

摘要:The present invention relates to a process for synthesising and obtaining biobased hydroxyl-terminated telechelic oligomers, such as biobased hydroxyl-terminated polybutadiene, by means of a degradation reaction via metathesis of industrial rubbers and using fatty alcohols as chain transfer agents (CTA). In particular, the present invention relates to the synthesis and production of diols, polyols and polyesters based on a degradation reaction via metathesis between industrial rubbers or natural rubbers and essential oils, fatty acids, fatty alcohols and terpenes with R-OH and R-COO-R terminal groups, the chemical structure, molecular weight and properties of which can be controlled.
