On the exclusion of radical species in the ligand coupling reactions with pentavalent triarylbismuth derivatives

The presence of aryl radical species in the course of arylation reactions with tri and pentavalent organobismuth compounds has been studied by the use of an internal-trap containing reagent: tris(2- allyloxyphenyl)bismuth and its diacetate. The intervention of radical species can be excluded in C- and O-arylation under basic conditions as well as in copper catalyzed O- and N-arylation, as cyclized products were never detected in any of these reactions.

Intramolecular cyclopropylmethylation via non-classical carbocations

Cyclopropyl-cyclopropyl rearrangement can be achieved selectively by intramolecular trapping of cyclopropylmethyl carbenium ions with an internal nucleophile. This can be exploited as a useful method for the introduction of a cyclopropyl group into complex molecules using readily accessible disubstituted cyclopropane intermediates.
