Abstract
Aluminium caprolactamate (I) was prepared by the reaction of ε-caprolactam with isopropyliminoalane (II) in benzene. IR and 1H-NMR spectra of I in various solvents are described as well as low-temperature 1H-NMR spectra in hexane and dichlormethane. On the basis of these results together with the determination of molecular weights, structural arrangement was proposed for the dimer of I containing an eight-membered ring formed by two -O-C-N-bridges between aluminium atoms and two caprolactam ligands on each aluminium atom bonded through oxygen atom of carbonyl.Keywords
