摘要： Provided is a method of producing perfluoro(2-methylene-4-methyl-1,3-dioxolane), the method including at least following processes (1) to (3):
(1) reacting at least one of perfluoro(2,4-dimethyl-2-fluoroformyl-1,3-dioxolane) and a hydrolysis product thereof with a basic aqueous solution containing one or more cations selected from the group consisting of alkali metal ions and alkaline earth metal ions and then separating a liquid containing produced perfluoro(2,4-dimethyl-1,3-dioxolane-2-yl)carboxylic acid alkali metal salts or perfluoro(2,4-dimethyl-1,3-dioxolane-2-yl)carboxylic acid alkaline earth metal salts by a liquid separation operation;
(2) performing one or more water content reduction treatments selected from the group consisting of water evaporation and water adsorption on the liquid containing the obtained perfluoro(2,4-dimethyl-1,3-dioxolane-2-yl)carboxylic acid alkali metal salts or perfluoro(2,4-dimethyl-1,3-dioxolane-2-yl)carboxylic acid alkaline earth metal salts to obtain perfluoro(2,4-dimethyl-1,3-dioxolane-2-yl)carboxylic acid alkali metal salts or perfluoro(2,4-dimethyl-1,3-dioxolane-2-yl)carboxylic acid alkaline earth metal salts in a solution state or a solid state; and
(3) causing a decarboxylation reaction in a liquid phase system with the obtained perfluoro(2,4-dimethyl-1,3-dioxolane-2-yl)carboxylic acid alkali metal salts or perfluoro(2,4-dimethyl-1,3-dioxolane-2-yl)carboxylic acid alkaline earth metal salts in a solution state or a solid state to produce perfluoro(2-methylene-4-methyl-1,3-dioxolane).

摘要： The purpose of the present invention is to provide: an aromatic compound having a specific substituent, said aromatic compound being a coating-type organic semiconductor material that has high carrier mobility, high heat resistance and adequate solubility; an organic semiconductor layer which uses this aromatic compound; and an organic thin film transistor. The purpose is achieved by an aromatic compound which is represented by formula (1-I) or (1-II).
In formulae (1-I) and (1-II), Ar represents a monocyclic ring or the like; each of X 1 and X 2 represents an oxygen atom or the like; each of Y 1 and Y 2 represents CR 6 or the like; each of R 1 to R 6 represents a hydrogen atom or the like; and at least one of the R 1 to R 6 moieties is a group that is represented by formula (2).
In formula (2), A represents a specific alkenyl group or the like; each of 1 and n represents 0 or 1; m represents an integer from 1 to 20; and each of Z 1 and Z 2 represents a hydrogen atom or the like.
