A homoanomeric effect is found to stabilize the 1,2-dimethoxyethyl radical (CH3O–ĊH–CH2OCH3) in a conformation in which the singly-occupied orbital at the radical centre is approximately coplanar with the p-type lone pair on the α-oxygen and with the β-C–O bond. The magnitude of this stabilization is predicted to be ~10–12 kJ mol−1 at the G3(MP2)-RAD and CBS-RAD levels of theory.
