Aminal radicals were generated by reduction of the corresponding amidine or amidinium ion. The intermediate radicals participate in C–C bond-forming reactions to produce fully substituted aminal stereocenters. No toxic additives or reagents are required. More than 30 substrate combinations are reported, and chemical yields are as high as 99%.

Aminal radicals were generated and used in synthetic reactions for the first time. Aminal radicals are formed from aminals by radical translocation using AIBN and a stoichiometric hydrogen atom donor, or by SmI2 reduction of N-acyl amidines or amidinium ions in the presence of a proton source. Aminal radicals were found to participate in inter- and intramolecular C–C bondformingreactions with electron
