METHOD FOR PRODUCING AROMATIC UNSATURATED COMPOUND

摘要

A method for producing an aromatic unsaturated compound represented by the formula (4): (wherein Ar represents an aromatic group which may be substituted or a heteroaromatic group which may be substituted, and Y represents an electron-withdrawing group) is disclosed which includes a step for reacting (a) a compound represented by the formula (1): (wherein Ar is as defined above), with (b) a compound represented by the formula (2): (wherein Y is as defined above, and Z represents a lower alkoxy), or a compound represented by the formula (3): (wherein Y and Z are as defined above), in the presence of (c) an acid or a compound which produces a mineral acid through hydrolysis.
