Abstract
This paper describes the structural studies of 2-phenyl-9,9?-dimethyl-2,2?-spirobis(1,3,2-?5-benzoxazarsoline) 5, 2-phenyl-8,8?-dimethyl-2,2?-spirobis(1,3,2-?5-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 AsN, AsC and AsO bonds in these compounds was established by NBO studies.
