Filace, Fabiana published the artcileSilyl Assistance in the Intramolecular Addition of Pyridyl Radicals onto Pyridines and Quinolines, Quality Control of 39856-58-1, the publication is European Journal of Organic Chemistry (2016), 2016(10), 1891-1896, database is CAplus.
The first example of a stable acylazinium salt obtained by an intramol. acylpyridine-centered radical attack on azine nitrogen atoms is reported. Depending on the relative position of the bromo substituent on the attacking aminopyridine ring, it is possible to obtain selectively either the N-attack product or a different C-attack derivative A rationale for this pathway selectivity was obtained from quantum mech. calculations
