Formation, Structural Characterization, and Calculated NMR Chemical Shifts of Selenium-Nitrogen Compounds from SeCl4 and ArNHLi (Ar = supermesityl, mesityl)
Abstract
Supermesityl selenium diimide [Se{N(C6H2
tBu3-2,4,6)}2; Se{N(mes*)}2] can be prepared in
a good yield from the reaction of SeCl4 and (mes*)NHLi. The molecule adopts an
unprecedented anti,anti-conformation, as deduced by DFT calculations at PBEO/TZVP level
of theory and supported by 77Se NMR spectroscopy and a crystal structure determination. An
analogous reaction involving (C6H2Me3-2,4,6)NHLi [(mes)NHLi] unexpectedly lead to the
reduction of selenium and afforded the selenium diamide Se{NH(mes)}2 that was
characterized by X-ray crystallography and 77Se NMR spectroscopy. The Se-N bonds of
1.847(3) and 1.852(3) Å show normal single bond lengths. The
