Title:
CONDENSATION REACTION BY METAL CATALYST
Document Type and Number:
WIPO Patent Application WO/2007/066617
Kind Code:
A1
Abstract:
Disclosed is a method for producing an azoline compound represented by the general formula (3) below, which is characterized in that a carboxylic acid or a carboxylic acid derivative represented by the general formula (1) below is reacted with an aminochalcogenide represented by the general formula (2) below in the presence of a compound containing a group 12 metal element of the periodic table. R1CO2R2 (1) (In the formula (1), R1 represents a hydrocarbon group, an alkoxy group, an alkoxycarbonyl group, a halogen atom, a substituted amino group, a substituted carbamoyl group or a heterocyclic group; and R2 represents a hydrogen atom, an alkyl group or an aryl group.) [Chemical formula 1] (2) (In the formula (2), R3, R4, R5 and R6 independently represent a hydrocarbon group, an alkoxy group, an alkoxycarbonyl group, a halogen atom, a substituted amino group, a substituted carbamoyl group or a heterocyclic group, or alternatively arbitrary two groups selected from R3, R4, R5 and R6 may combine together to form a ring; and Z1 represents an oxygen atom, a sulfur atom or a selenium atom.) [Chemical formula 2] (3) (In the formula (3), R1, R3, R4, R5, R6 and Z1 are as defined above.)
