A nickel-catalyzed, enantioselective, three-component fluoroalkylarylation of unactivated alkenes with aryl halides and perfluoroalkyl iodides has been described. This cross-electrophile coupling protocol utilizes a chiral nickel/BiOx system as well as a pendant chelating group to facilitate the challenging three-component, asymmetric difunctionalization of unactivated alkenes, providing direct access
reaction via the palladium-catalyzed insertion of isocyanide has been established. Isocyanides were inserted into C−O bond under mild conditions, using the readily available allylester as the starting materials. In addition, the intramolecular acyl transfer from the ester group oxygen atom to the isocyanide nitrogen atom afforded imide derivatives in moderate to excellent yields. Additionally, this

A Ni-catalyzed enantioselective reductive three-component alkylalkenylation of β,γ-alkenyl ketones with cis-alkenyl iodides and fluoroalkyl iodides in the presence of Mn is reported. By leveraging five-membered nickellacycles stabilized by pendant ketone group and chiral bis(oxazoline) (BiOx) ligand, this three-component protocol allows efficient access to enantioenriched β-alkenyl ketones from simple
Novel organic glass with a high refractive index comprising a copolymer of (a) a diallyl isophthalate monomer, (b) an allyl benzoate monomer and (c) a diester of maleic acid and/or diester of fumaric acid monomer, which also shows excellent light resistance and excellent other physical properties such as excellent moldability, high impact resistance, high dimension stability, excellent mechanical processing properties, excellent dyeability and excellent hard coating property, and is useful as a material for optical or optoelectronic parts such as lenses, prisms, reflecting mirror and window materials.
