PROBLEM TO BE SOLVED: To provide a trifluoromethylthiophenium derivative salt useful as an intermediate for synthesizing medicines and agrochemicals, a method for producing the same and a method for producing a trifluoromethyl group-containing compound using the same. SOLUTION: The trifluoromethylthiophenium derivative salt is represented by general formula (1) (wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 and R 9 are each independently hydrogen, methyl, ethyl or the like; and X is fluorine, trifluoromethanesulfonyl or the like). The method for producing the same is provided. Various trifluoromethyl group-containing compounds are produced by using the same as a trifluoromethylating agent. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a carrier for separation and a method for separation of a compound which enable a chemical reaction to be performed in a liquid phase, enable a specific compound to be separated readily from the liquid phase after completion of the reaction, enable the separated compound to be evaluated by structural analysis or the like while the compound being bound to the carrier, and further enable the compound to be separated easily from the carrier. SOLUTION: The carrier for separation includes a reaction site capable of reacting with other compounds on a benzene ring, and has a long chain group having a specific number or more of carbon atoms at each of the ortho- and para-positions of the reaction site through an oxygen atom.

摘要:
A microencapsulated catalyst is prepared by dissolving or dispersing a catalyst in a first phase (for example an organic phase), dispersing the first phase in a second, continuous phase (for example an aqueous phase) to form an emulsion, reacting one or more microcapsule wall-forming materials at the interface between the dispersed first phase and the continuous second phase to form a microcapsule polymer shell encapsulating the dispersed first phase core and optionally recovering the microcapsules from the continuous phase. The catalyst is preferably a transition metal catalyst and the encapsulated catalyst may be used for conventional catalysed reactions. The encapsulated catalyst may recovered from the reaction medium and re-cycled.

PROBLEM TO BE SOLVED: To provide a method for producing an optically active cyclopropane carboxylic acid ester compound rich in cis-form. SOLUTION: The optically active cyclopropane carboxylic acid ester compound of formula (4) (wherein R 5 represents an alkyl group or the like; R 6 represents an alkyl group or the like; and * represents the asymmetric center) is produced by reacting a diazoacetic acid ester and a compound represented by formula (3) in the presence of an asymmetric copper complex which is obtained by reacting a copper compound with an optically active salicylideneaminoalcohol compound having a specific structure.
