Abstract

Abstract The reaction of the di-lithiated oxamide of 1 with two equivalents of SnCl 2 provided the tin trans-oxamide 3. In solution, spectroscopic analysis suggests exclusively the formation of a trans-oxamide (trans-3). However, the solid state shows an atypical cis- oxamide (cis-3), where the oxamide fragment acts as an anti-Janus head ligand. An 119 Sn- NMR variable temperature experiment ([D 8] THF) of the trans-oxamide (trans-3) was ...
