Abstract
[formula: see text] Dynamic NMR analysis of conformationally mobile and rigid 2-tributylstannyl-N-methylpiperidines revealed an unexpected conformational effect that is manifested in a small energy difference between conformers in which the tin is equatorial and axial. The major reason appears to be a distortion of the conformer in which the C-2-Sn bond is synclinal to the nitrogen lone pair.Keywords
