Beschreibung
Zusammenfassung:	A method of producing styrene derivatives expressed the general formula (2) by reacting a benzaldehyde derivative expressed by the general formula (1) with dibromomethane under the existence of zinc metal as well as an active chloride for producing various types of oxystyrene which are polymerized monomers as a photoresist material used in a high density integrated circuit process from easily available materials which also can easily be handled: (wherein R indicates a an alkyl group, alkoxyalkyl group, an alkylcarbonyl group, an alkoxycarbonyl group, a 5 or 6-atom heterocylclic groups, or an alkylsilyl group); (wherein R indicates any of the same substituents as those described above.)
