摘要:The present invention relates to a process for the preparation of trifluoromethylated derivatives of the formula CF 3 CClâ•?CHCH 2 OC(â•?O)R, wherein R is unsubstituted or substituted C 1 to C 6 straight chain or branched alkyl, unsubstituted or substituted C 3 to C 7 cycloalkyl, unsubstituted or substituted C 2 to C 12 alkenyl, a benzyl group unsubstituted or substituted with R', a phenyl group unsubstituted or substituted with R'; R' is an unsubstituted or substituted C 1 to C 6 straight chain or branched alkyl; and wherein where R and/or R' are substituted each is substituted with R', by reaction of HCFC-353 with carboxylic acid salts. The trifluoromethylated derivatives, particularly CF 3 CClâ•?CHCH 2 OC(â•?O)CH 3 , are versatile intermediates for the synthesis of a wide variety of trifluoromethylated organic compounds, which find utility as pharmaceuticals, agricultural chemicals, and materials such as liquid crystals.

标 题:Process for the synthesis of o-substituted oxime compounds
发明人：CHEMPOLIL THOMAS MATHEW
权利人:ALLIED SIGNAL INC
摘要:A novel process for the production of O-substituted oximes is disclosed. The process involves reacting an oxime with an alkali-metal hydroxide optionally in a solvent which forms an azeotrope with water to form a mixture of the alkali metal salt of the oxime and water, removing all or a portion of the water by distilling the mixture azeotropically and reacting the distilled mixture with an alpha halo carboxylic acid.
