Notes:
The conformations of the isopropyl groups and the barriers to conformational interconversion in methyl N,N-diisopropylcarbamate, its thiol and seleno analogues have been studied by 1H d.n.m.r. In the diselenocarbamate, complete bandshape analysis of the Se-methyl proton signals proves unequivocally that the conformational interconversion takes place by rotation of one isopropyl group at a time rather than by a concerted rotation of both groups. The populations and barriers observed for the new compounds fit well into the general scheme found previously for other N,N-diisopropylamides and -thioamides.
