| abstract | (57) [Summary] General formula I: [Wherein, R a and R b are the same or different and each represents a hydrogen atom or an optionally substituted C 1 -C 20 -alkyl group, an optionally substituted C 8 -C 10 -aryl group, An optionally substituted C 7 -C 12 -aralkyl group, an optionally substituted heteroaryl group or an optionally substituted heterocycloalkyl group, except for a self-condensation product of formaldehyde]. In a process for preparing Of the formula III in the presence of a catalyst Wherein R a and R b in the above formula represent the same as described above, and at least one of the groups R a and R b represents a group other than a hydrogen atom. Using Formula IV: [Wherein, R 1 and R 3 are the same or different and each have an aliphatic group having 1 to 30 carbon atoms, an aryl group which may be substituted, an aralkyl group which may be substituted and / or R 2 represents a hydrogen atom or a group R b CH (OH); R 4 has a hydrogen atom, a halogen atom, a nitro group or a cyano group, and has 1 to 30 carbon atoms aliphatic group, an optionally substituted aryl group, an optionally substituted aralkyl group, an optionally substituted heteroaryl group, an alkoxy group -OR 5, a thioether group -SR 6, an amino group -NR 7 R 8 represents an acyl group -COR 9 or an ester group -COOR 10 , wherein the groups R 5 , R 6 , R 7 , R 8 and R 9 represent the groups described for R 1 and R 10 represents C 1 -C 30 - is alkyl or substituted There C 3 -C 5 is or R 3 and R 4 also represent an aryl group or an aralkyl group together - alkylene bridge-like parakeets, C 3 -C 5 - alkenylene bridged parakeet, C 6 -C 14 - Forming an arylene bridge, a C 7 -C 14 -aralkylene bridge or a C 8 -C 14 -aralkenylene bridge, where A is due to the electrically neutral charge on the triazolium cation Represents an equivalent weight of anion having one or more negative charges of the formula [1]. |
