• From stoichiometry to catalysis: electroreductive coupling of alkynes and carbon dioxide with nickel-bipyridine complexes. Magnesium ions as the key for catalysis
  作者：Sylvie Derien、Elisabet Dunach、Jacques Perichon

  DOI：10.1021/ja00022a037

  日期：1991.10

  The incorporation of carbon dioxide into nonactivated alkynes catalyzed by electrogenerated nickel-bipyridine complexes affords alpha,beta-unsaturated acids in moderate to good yields. The electrocarboxylation reaction was undertaken on a preparative scale in the presence of a sacrificial magnesium anode: the formation of acids from alkynes is stoichiometric with respect to the nickel complex if performed in a two-compartment cell but can be made catalytic in a single-compartment cell. An intermediate nickelacycle was isolated from the reaction with 4-octyne. The cleavage of this metallacycle by magnesium ions is the key step to explain catalysis.
• Novel polymer and chemically amplified resist composition containing the same

  公开（公告）日：2005-07-14

  The present invention provides a chemically amplified resist composition including a novel polymer, a photoacid generator, and a solvent: The chemically amplified resist can form a resist pattern that is excellent in adhesiveness with a low dependency to the substrate, transparency at the far ultraviolet wavelength range such as KrF Excimer laser or ArF Excimer laser, dry etch resistance, sensitivity, resolution, and developability. In addition, the polymer contains a maximum number of saturated aliphatic rings to enhance etching resistance, and additionally includes an alkoxyalkyl acrylate monomer introduced as a solution to the problem with the conventional polyacrylate resist in regard to edge roughness of the pattern, to form a uniform edge of the pattern because the alkylalcohol compound generated together with a formaldehyde and a carboxylate compound by a deprotection reaction of the alkoxyalkyl acrylate monomer with an acid acts as a solvent or an antifoaming agent in the pattern.
