Abstract:
1. A method for producing a cyclic carbamate ester represented by the general formula (1), comprising the step of conducting a reaction using, as starting materials, an organic compound represented by the general formula (2) or (3) which has at least two halogen atoms per molecule, an amine represented by the general formula (4), and carbon dioxide, wherein R1, R2, R3, R4 and R5 may be the same or different groups or be linked cyclic groups and represent a non-substituted or substituted aryl group, hydrogen, a hydroxyl group, an alkyl group having 1 to 12 carbon atoms which has at least one halogen or at least one substituent, an alkenyl group, an alkynyl group or a cycloalkyl group, and the substituent represents an aryl group, an alkyl group, an alkenyl group, an alkynyl group, an alkoxy group, a carbonyl group, a carboxyl group, a hydroxyl group, a mercapto group, a halogen, a sulfonyl group or an amino group; and n represents an integer satisfying the following relationship: 0≦n≦4, wherein X 1 and X 2 represent a halogen atom and may be the same or different halogen atoms; R2, R3, R4, R5, R6 and R7 may be the same or different groups or be linked cyclic groups and represent a non-substituted or substituted aryl group, hydrogen, a hydroxyl group, an alkyl group having 1 to 12 carbon atoms which has at least one halogen or at least one substituent, an alkenyl group, an alkynyl group or a cycloalkyl group, and the substituent represents an aryl group, an alkyl group, an alkenyl group, an alkynyl group, an alkoxy group, a carbonyl group, a carboxyl group, a hydroxyl group, a mercapto group, a halogen, a sulfonyl group or an amino group; and n represents an integer satisfying the following relationship: 1≦n≦4, wherein X 1 and X 2 represent a halogen atom and may be the same or different halogen atoms; and R4 and R5 are as defined above, wherein R1 is as defined above.
