4-Methoxystyrene 1 underwent dimerization to 1,4-diphenylbutane derivatives 5 and 6 in presence of CAN in methanol. But in ethanol the same reaction afforded a tetralone derivative along with 5 and 6. 3,4-Dimethoxystyrene 10 underwent dimerization in presence of CAN in methanol to afford acyclic as well as cyclic products. 3,4,5-Trimethoxystyrene 12 in presence of CAN in methanol afforded only the cyclized dimers, the tetralone 21 and the tetralin derivative 22.
