POLYVALENT VINYL AROMATIC COMPOUND AND METHOD FOR PRODUCING SAME

摘要

A polyvalent vinyl aromatic compound represented by chemical formula (4) is produced by reacting (1) a specific vinyl aromatic compound and (2) a specific vinyl compound in the presence of (3-1) a metal complex and (3-2) a percarboxylic acid or a hypervalent iodine compound so that a vinyl group derived from the vinyl compound is introduced onto a carbon atom that is adjacent to the carbon atom to which a vinyl group is bonded in the vinyl aromatic compound. (In the formula, Ar represents a monocyclic aromatic hydrocarbon group or the like; R1a represents a -CH2OC(=O)R4 group or the like; R2 represents a hydrogen atom or the like; R3 represents a hydrogen atom or the like; A represents an alkyl group having 1-20 carbon atoms, or the like; and n represents an integer of 1-m.)
