1,4,6,9-Tetraoxa-5λ4-selena-spiro[4.4]nonane – A Combined Theoretical and Experimental Study†
Dedicated to Professor Heinrich Nöth on the Occasion of his 80th Birthday
Abstract
The symmetric spiro-selenurane derived from ethylene glycol, 1,4,6,9-tetraoxa-5λ4-selena-spiro[4.4]nonane, was prepared from selenium tetrachloride and ethylene glycol and its molecular structure was determined by single crystal X-ray diffraction. NBO analyses for the title compound and a related compound were conducted to assess the role of the stereochemical active lone pair on the selenium atom on the structure.
