Paragraph 0157; 0158, (2013/12/02)
A manufacturing method of an imidazole compound represented by a formula (1) below includes reacting 1-arylimidazole with a halogen-atom substituted compound. For performing this reaction, in a reaction system, a mole number Nf(2) [mol] of the halogen-atom substituted compound and a total volume Vsol [liter] of an ether solvent having at most 5 carbon atoms satisfy a relationship of Vsol/Nf(2)≤3. In the formula (1): R1 and R4 represent a substituent and the like; Z1 represents a group of atoms necessary for forming a hydrocarbon cyclic group and the like; R2 and R3 represent a bond, a hydrogen atom or an aromatic hydrocarbon group; Z2 represents a group of atoms necessary for forming a five-membered hydrocarbon ring and the like together with C-C; and m represents an integer of 1 to 5.
The basicity gradient-driven migration of iodine: Conferring regioflexibility on the substitution of fluoroarenes

Six different fluoroarenes were submitted to the same transformations. Direct deprotonation with alkyllithium or lithium dialkylamide as reagents and subsequent carboxylation afforded the acids 1, 6, 11, 16, 18, and 23. If the aryllithium intermediate was trapped with iodine rather than with dry ice, an iodofluoroarene (2, 7, 12, 17, 19, and 24) was formed. This, upon treatment with lithium diisopropylamide, underwent deprotonation and iodine migration. The resulting new aryllithium species was intercepted either by carboxylation, to give the acids 3, 8, 13, 20, and 25, or by neutralization, to produce the iodofluoroarenes 4, 9, 14, 21, and 26. The latter family of compounds was converted into another set of acids 5, 10, 15, 22, and 27 by subsequent treatment with butyllithium or isopropylmagnesium chloride and carbon dioxide.
