The present invention relates to a gas-barrier resin composition, including: a gas-barrier resin (A) having an oxygen permeability coefficient of 1.0×10-14 (cm3·cm/cm2·s·Pa) or less; and a copolymer (B) containing monomer structural units represented by the formula (1), the formula (2), and the formula (3):
where: R1 represents a hydrogen atom or a methyl group; R2 represents a hydrocarbon group having 1 to 20 carbon atoms that may be substituted with a halogen atom, a hydroxy group, an alkoxy group, or an amino group; l, m, and n represent numerical values representing molar proportions of the respective monomer structural units, and n may represent 0; and p represents an integer of from 1 to 4, wherein a ratio of a mass of the copolymer (B) to a total mass of the gas-barrier resin (A) and the copolymer (B) is from 1 mass% to 40 mass%. Preferred as the gas-barrier resin (A) are a vinyl alcohol-based resin (A1), a polyamide-based resin (A2), and a polyester-based resin (A3). The present invention can provide a resin composition ameliorated in low flexibility and low impact resistance, which are drawbacks of a gas-barrier resin, without impairing excellent gas barrier properties of the gas-barrier resin.

efficient electrochemical Ni-catalyzed alkene hydrogenation is described. The reaction features outstanding substrate generality and functional group compatibility, and distinct chemoselectivity. Notably, hydrodebromination of alkyl and aryl bromides can be realized using the same reaction system with a different ligand, and high chemoselectivity between hydrogenation of alkene and hydrodebromination could
