The rates of β-aryl migration in vinyl cations were determined by laser flash photolysis of the corresponding vinyl bromides in acetonitrile. β-Anisyl migration occured very rapidly (k>/=10E8 s-1). β-Phenyl migration in Ph(An)C=C+-Ph <*> An-C+=CPh2 was relatively slow process (k=7.4 x 10E6 s-1 at 273 deg K).
