Abstract: | This paper describes the structural studies of 2-phenyl-9,9′-dimethyl-2,2′-spirobis(1,3,2-λ5-benzoxazarsoline) 5, 2-phenyl-8,8′-dimethyl-2,2′-spirobis(1,3,2-λ5-benzoxazarsoline) 6 by 1H,13C,15N NMR in 2H6]DMSO and CDCl3. The solid state studies were made by X-ray experiments. Infrared spectroscopy was obtained in CDCl3 and the vibrational signals were assigned using DFT calculations. The nature of the As–N, As–C and As–O bonds in these compounds was established by NBO studies. |
