carbon atoms remains elusive. Here we report the isolation of a compound with a one-electron σ-bond between carbon atoms by means of the one-electron oxidation of a hydrocarbon with an elongated C–C single bond5,6. The presence of the C•C one-electron σ-bond (2.921(3) Å at...

6.36. The nucleophilic attack is an axial addition and takes place preferentially from the top face of the carbon–carbon double bond to give directly the chair, rather than a twist-boat from the bottom face attack (cf. Fig. 6.29). Subsequent protonation of the enolate intermediate then ...
