Aryl radicals bearing an aldimino functional group as part of an ortho substituent cyclized by addition to C and/or N of the imino group.When the choice was between 5-exo closure to C and 6-endo closure to N, the former predominated.However, 6-endo closure to C predominated over 5-exo cyclization to N in isomeric imines.Absolute values of cyclization rate constants were determined and an explanation for the unusual 6-endo preference is offered.Chiral induction in 6-endo cyclization to C of an aldimine from D-glyceraldehyde acetonide was observed, and its sense was determined.

The previously unknown bistributyltin benzopinacolate was prepared by photolysis of benzophenone in the presence of bistributyltin and used for thermal formation of aryl radicals that undergo subsequent intramolecular addition to an imine bond in an ortho-substituent.
