26 Mar 1991TL;DR: In this paper, a method for depositing a film of a desired material on a substrate comprises dissolving at least one reagent in a supercritical fluid comprising at least 1 solvent, and a chemical reaction is induced in the resulting reaction is deposited on the substrate surface.
Abstract: A method for depositing a film of a desired material on a substrate comprises dissolving at least one reagent in a supercritical fluid comprising at least one solvent. Either the reagent is capable of reacting with or is a precursor of a compound capable of reacting with the solvent to form the desired product, or at least one additional reagent is included in the supercritical solution and is capable of reacting with or is a precursor of a compound capable of reacting with the first reagent or with a compound derived from the first reagent to form the desired material. The supercritical solution is expanded to produce a vapor or aerosol and a chemical reaction is induced in the vapor or aerosol so that a film of the desired material resulting from the chemical reaction is deposited on the substrate surface. In an alternate embodiment, the supercritical solution containing at least one reagent is expanded to produce a vapor or aerosol which is then mixed with a gas containing at least one additional reagent. A chemical reaction is induced in the resulting mixture so that a film of the desired material is deposited.

TL;DR: A new, electrophilic difluoromethylthiophthalimide 3 was developed that allows the diffluorometHylthiolation of a wide range of nucleophiles including aryl/vinyl boronic acids, alkynes, amines, thiols, β-ketoesters, and oxindoles and electron-rich heteroarenes.
Abstract: A new, electrophilic difluoromethylthiolating reagent N-difluoromethylthiophthalimide 3 was developed. Reagent 3 can be readily synthesized in four steps from easily available starting materials phthalimide and TMSCF2H. N-difluoromethylthiophthalimide 3 is a powerful electrophilic difluoromethylthiolating reagent that allows the difluoromethylthiolation of a wide range of nucleophiles including aryl/vinyl boronic acids, alkynes, amines, thiols, β-ketoesters, and oxindoles and electron-rich heteroarenes such as indole, pyrrole, 1H-pyrrolo[2,3-b]pyridine, imidazo[1,2-a]pyridine, aminothiazole, isoxazole, and pyrazole under mild conditions.

TL;DR: In this paper, a new method for the preparation of Ni2+-Fe3+ LDH material with high crystallinity and well-defined hexagonal shapes was successfully developed by using urea as hydrolysis agent and trisodium citrate as chelating reagent under a hydrothermal condition at 150 °C for two days.
