Radical addition to "cation pool". Reverse process of radical cation fragmentation

J Am Chem Soc. 2005 May 25;127(20):7324-5. doi: 10.1021/ja0511218.

Abstract

The reaction of an N-acyliminium ion with an alkyl iodide and hexabutyldistannane took place to give the alkylation product. A mechanism involving the addition of an alkyl radical to an N-acyliminium ion to produce the corresponding radical cation has been suggested.
