Durch Bromirung ausgeloeste Umlagerung tertiaerer Allylalkohole: Der Einfluss eines Fluor-Substituent auf Reactionsgeschwindigkeit und reactionsverlauf

The allyl alcohol bearing a methyl and a t-butyl group at the hydroxylated position was found to undergo a rearrangement when treated with bromine (or N-bromosuccinimide) in an aqueous medium and to afford a product mixture containing two regioisomeric ketones and one oxirane.Introduction of an additional methyl group or a fluorine atom at the non-terminal olefinic center led to a more selective discrimination between potential migratory groups.As the result of an exclusive t-butyl shift only one product, a ketone, was formed in both cases.Whereas the reaction rate only was slightly affected by the additional methyl group, it was substantually decreased by the fluorine atom.
SYNTHESE A L'AIDE DE SULFONE-XXV. SUBSTITUTION SUR DES SULFONES: L'ANION PHENYLSULFINATE COMME GROUPE PARTANT DANS LA SUBSTITUTION DES SULFONES ALLYLIQUES PAR DES REACTIFS DE GRIGNARD EN PRESENCE DE SELS DE CUIVRE

Displacement reactions of the sulphinate anion from sulfones by Grignard reagents with copper catalysis take place readily with allylic sulphones.The regio chemistry and stereochemistry of the reaction are discussed.

A Method for preparing alpha-olefins from Biomass-derived fat and oil
-
Paragraph 0191-0202; 0224-0227, (2020/09/22)
The present invention relates to a method for preparing alpha-olefins from biomass-derived fats and oils. According to the preparation method, all of the various saturated or unsaturated fatty acids in the biomass-derived fats and oils can be prepared into alpha-olefins, and a conventional problem that the saturated fatty acids do not participate in a reaction or a mixture is generated due to polyunsaturated fatty acids can be solved. Thus, the present invention can be advantageously used to prepare alpha-olefins from biomass.

An efficient CuPd nanoparticle (NP) catalyst (3 nm CuPd NPs deposited on carbon support) is designed for catalyzing electrochemical allylic alkylation in water/isopropanol (1:1 v/v) and 0.2 m KHCO3 solution at room temperature. The Pd catalysis was Pd/Cu composition-dependent, and CuPd NPs with a Pd/Cu ratio close to one are the most efficient catalyst for the selective cross-coupling of alkyl halides and allylic halides to form C?C hydrocarbons with product yields reaching up to 99 %. This NP-catalyzed electrochemical allylic alkylation expands the synthetic scope of cross-coupling reactions and can be further extended to other organic reaction systems for developing green chemistry electrosynthesis methods.
