摘要

Mechanism of a Novel Spirocyclisation Reaction; Intramolecular Oxygen Transfer to Carbon Radicals by Nitro Groups ... Upendra P. Topiwala and Donald A. Whiting" Chemistry Department, The University, Nottingham, UK NG7 2RD ... A mechanism for the novel radical spirocyclisation reaction 1 -+ 2 is proposed, and is shown by isotopic labelling to involve transfer of oxygen from an aromatic nitro function to carbon in a cyclohexadienyl radical.
