Condensation reaction by metal catalyst

Abstract

The invention relates to a method for producing an azoline compound represented by the general formula (3): wherein R1 represents an optionally substituted hydrocarbon group, an optionally substituted alkoxy group, an optionally substituted alkoxycarbonyl group, a halogen atom, a substituted amino group, a substituted carbamoyl group or an optionally substituted heterocyclic group; R3, R4, R5 and R6 may be the same or different and each represents a hydrogen atom, an optionally substituted hydrocarbon group, an optionally substituted alkoxy group, an optionally substituted alkoxycarbonyl group, a halogen atom, a substituted amino group, a substituted carbamoyl group or an optionally substituted heterocyclic group; two arbitrary groups selected from R3, R4, R5 and R6 may bond to each other to form a ring; and Z1 represents an oxygen atom, a sulfur atom or a selenium atom; comprising reacting a carboxylic acid or a carboxylic acid derivative represented by the general formula (1): R1CO2R2  (1) wherein R1 is as defined above; R2 represents a hydrogen atom, an optionally substituted alkyl group or an optionally substituted aryl group; and R1 and R2 may bond to each other to form a ring; with an aminochalcogenide represented by the general formula (2): wherein R3, R4, R5, R6 and Z1 are as defined above; in the presence of a compound containing a group 12 metal element in the periodic table.
