Preparation method of 1, 1-disubstituted olefin

The invention provides a preparation method of 1, 1-disubstituted olefin. The preparation method includes the steps of A), under the catalysis of a metallic nickel compound, allowing a compound as shown in formula (II) to have reaction with Grignard reagent as shown in formula (III) under protective atmosphere to obtain the 1, 1-disubstituted olefin as shown in formula (I), wherein R1 is alkyl, substituted alkyl, aryl or substituted aryl, and R2 is aryl or substituted aryl. Compared with the prior art, the preparation method has the advantages that the method is simple in raw material, wide in raw material source, mild in reaction condition and high in selectivity, only the 1, 1-disubstituted olefin is prepared, and the isomer of the 1, 1-disubstituted olefin does not exist.

Nickel-Catalyzed Allylic C(sp2)–H Activation: Stereoselective Allyl Isomerization and Regiospecific Allyl Arylation of Allylarenes

Stereoselective allyl isomerization and regiospecific allyl arylation reactions of allylarenes with a catalytic system comprising nickel(II) with an aryl Grignard reagent were studied. Both reactions are triggered by allylic internal C(sp2)–H activation by in-situ-formed Ni0, which is inserted into the C–H bond at the 2-position of the allyl moiety without a directing group. The isomerization of allylarene to 1-propenylarene favors the E isomer and proceeds with quantitative conversion. The arylation takes place through oxidative cross-coupling of allylarenes with excess Grignard reagent. It occurs regiospecifically at the position of C(sp2)–H activation and represents a new method for the synthesis of 1,1-disubstituted olefins. The results of deuterium labeling experiments reveal an alkenyl/alkyl mechanism involving allylic internal C(sp2)–H activation and multiple intermolecular 1,2-, 1,3-, and 2,3-hydride shifts. These methods represent new approaches to the functionalization of olefins, and the mechanistic investigations could be helpful for the discovery and design of new strategies for olefin functionalization.

Synthesis of 1,3-diarylpropenes through palladium-catalyzed mizoroki-heck and allyl cross-coupling reactions using hydrazones as ligands

The palladium-catalyzed synthesis of unsymmetrical 1,3-diarylpropenes from allyl esters through a Mizoroki-Heck-type reaction with aryl iodides followed by allyl cross-coupling with a variety of arylboronic acids was developed; the products are obtained in moderate to good yields by using a hydrazone-Pd(OAc) 2 system.

Selective arylation of 1,1-disubstituted olefins using a biphenyl-based phosphine in Heck coupling reactions

The biphenyl-based phosphine, 2-diphenylphosphino-2′-methylbiphenyl is an effective ligand for palladium-catalyzed terminal arylation of 1,1-disubstituted olefins with aryl bromides in DMF and K2CO3 as base. The yields of products are independent of the electronic properties of the aryl bromides, however, the nature of the olefin has a major effect.

Palladium-catalysed Desulphonylative Vinylation of Arenesulphonyl Chlorides under Solid-Liquid Phase-transfer Conditions

The reaction of arenesulphonyl chlorides (1a-n) with butyl acrylate (2a) in the presence of a catalytic amount of bis(benzonitrile)dichloropalladium under solid-liquid phase-transfer conditions gave the corresponding butyl(E)-3-arylprop-2-enoates (3a-n) in good yield.The alkenes (2b-g) could also be used in place of (2a).
