ResumoComplex formations among butadiene(BD), acrylic compounds(A) such as acrylonitrile(AN) and methyl methacrylate(MMA), and ethylaluminum dichloride (EtAlCl2 or Al) were investigated with cryoscopic measurement, NMR and UV spectroscopies.From the cryoscopic study on the benzene solution of ethylaluminum dichloride and acrylic monomers such as methacrylonitrile(MAN), acrylonitrile, and methyl methacrylate, the existence of some complexes such as [MAN·Al]2, [AN·Al]2, [AN·Al·AN]2, and [MMA·Al]2 was estimated. NMR and UV studies suggested the formation of ternary charge-transfer complexes such as [BD ···π MMA →σ Al] and [BD ···π AN→σAl].
