describe a modular, palladium catalyzed synthesis of aryl(hetero)aryl benzophenones and aryl benzoates from aryl(hetero)aryl halides using CHCl3 as the carbonyl source in the presence of KOH. The reaction occurs in tandem through an initial carbonylation to generate an aroyl halide, which undergoes coupling with arylboronic acids, bornonates, and phenols.

A pattern-forming method comprises patternwise exposing a predetermined region of a resist material film made from a photosensitive resin composition comprising a chemically amplified resist material to a first radioactive ray that is ionizing radiation or nonionizing radiation having a wavelength of no greater than 400 nm. The resist material film patternwise exposed is floodwise exposed to a second radioactive ray that is nonionizing radiation having a wavelength greater than the wavelength of the nonionizing radiation for the patternwise exposing and greater than 200 nm. The chemically amplified resist material comprises a base component, and a generative component that is capable of generating a radiation-sensitive sensitizer and an acid upon an exposure. The generative component comprises a radiation-sensitive sensitizer generating agent. The radiation-sensitive sensitizer generating agent comprises a compound represented by formula (A).

A chemically amplified resist material comprises a polymer component that is capable of being made soluble or insoluble in a developer solution by an action of an acid, and a generative component that is capable of generating a radiation-sensitive sensitizer and an acid upon an exposure. The radiation-sensitive acid-and-sensitizer generating agent or the radiation-sensitive acid generating agent included in the generative component comprises the first compound that is radiation-sensitive and second compound that is radiation-sensitive. The first compound includes a first onium cation and a first anion, and the second compound includes a second onium cation and a second anion that is different from the first anion. Each of an energy released upon reduction of the first onium cation to a radical and an energy released upon reduction of the second onium cation to a radical is less than 5.0 eV.
