Latest Patents
Minesaki's latest patents include a method for producing 1,1,1,5,5,5-hexafluoroacetylacetone. This production method involves obtaining a reaction mixture containing at least 1,1,1,5,5,5-hexafluoro-3-pentyn-2-one through the reaction of a 3,3,3-trifluoropropynyl metal with a trifluoroacetate. The process continues with the formation of the hexafluoroacetylacetone hydrate by contacting the reaction mixture with water in the presence of an acid. This method is industrially applicable and allows for the dehydration of the hydrate to produce the desired compound.
Another significant patent is the process for producing 4-substituted benzopyran derivatives. This process includes reacting a 2,2-bis(fluoromethyl)-6-(perfluoroalkyl)-2H-1-benzopyran-4-one with a perfluoroalkanesulfonic acid anhydride in the presence of a base. The result is a perfluoroalkanesulfonic 2,2-bis(fluoromethyl)-6-(perfluoroalkyl)-2H-1-benzopyran-4-yl ester. The process further involves reacting the benzopyranyl ester with carbon monoxide in the presence of a palladium complex compound and a base to obtain the carboxylic acid.
