  • Method of producing dicarboxylic acids
    申请人:The United States of America as represented by the Secretary of Agriculture

    公开(公告)日:2009-05-19
    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.
    一种生产二羧酸(例如,α,ω-二羧酸)的方法,通过将具有末端COOH的化合物(例如,不饱和脂肪酸如油酸)与至少含有一个碳-碳双键的第二代Grubbs催化剂在无溶剂的情况下反应,以产生二羧酸。该方法在惰性气氛(例如,氩气、氮气)中进行。此过程也适用于从大豆、油菜籽、海藻和亚麻籽油中获得的混合不饱和脂肪酸。

    Abstract2,5‐Dimethyl‐2,4‐hexadiene is a readily available and easily managable compound, whose symmetric and polymethylated dienic structure should be prone to engage in cross‐metathesis reactions with other alkenes, but this has not been apparently exploited so far. Here we show that this reactant enables the easy synthesis of tri‐ and tetra‐susbtituted alkenes (i. e. isobutylenyl and prenyl groups) from simple alkenes under mild reaction conditions, not only with the conventional 2nd generation Grubbs catalyst but also with other Grela‐type catalyts such as StickyCat,TM AquaMetTM and GreenCatTM. The use of liquid and low volatile 2,5‐dimethyl‐2,4‐hexadiene avoids the use of gaseous alkene reactants and, besides, showcases the reactivity of polyisoprene (rubber), thus allowing to optimize the reaction conditions for rubber upcycling, after metathesis reaction of the pristine or used polymer with simple alkenes. These results bring low volatile isoprene‐type compounds as privileged poly‐substituted reactants for alkene cross‐metathesis reactions.

    Alkyltitanium alkoxides generally serve as nucleophiles in reactions with carbonyl compounds and cross-coupling. Their application as reductants is known but remains underdeveloped. Here, we report that irradiation with visible light makes these organometallic compounds efficient reducing agents for the dehalogenation of 1,2- and 1,3-haloalcohols. This reaction was utilized for the reduction of epoxides
