- Molecular structure and conformational properties of triflamide derivatives in the gas phase—Part II: 6‐Iodo‐3‐(triflamidomethyl)‐4‐triflyl‐1,4,2,7‐oxaazadisilepane and 2,2,4,4‐tetramethyl‐6,8‐bis (triflyl)‐3‐oxa‐6,8‐diaza‐2,4‐disilabicyclo[3.2.2]nonane by gas‐phase electron diffraction and theoretical calculations Bagrat A. Shainyan Alexey V. Eroshin Sergey A. Shlykov Journal of Physical Organic Chemistry Abstract6‐Iodo‐3‐(triflamidomethyl)‐4‐triflyl‐1,4,2,7‐oxazadisilepane 1 and the product of its cyclization, 2,2,4,4‐tetramethyl‐6,8‐bis (triflyl)‐3‐oxa‐6,8‐diaza‐2,4‐disilabicyclo[3.2.2]nonane 2, have been studied by gas‐phase electron diffraction and DFT calculations. The conformational equilibrium in the gas phase was shown to include three and two conformers for 1 and 2, respectively, in contrast to only one conformer determined by single crystal X‐ray diffraction. The structural analysis of the conformers was performed and the pathways of the conformational transitions were analyzed. 10.1002/poc.4613 http://onlinelibrary.wiley.com/termsAndConditions#vor
