The conjugate addition of α-amino radicals to alkenylpyridines has been accomplished by the synergistic merger of Br?nsted acid and visible light photoredox catalysis. Key to reaction development was the protonation of the alkenylpyridines that transientl

A study of charge transfer equilibria between a series of cis- and trans-4-styrylpyridines and cis- and trans-1-(4-X-phenyl)-2-(4-pyridyl)cyclopropanes with iodine has been carried out in CCl4.Acidity constants for these heteroaromatic compounds were determined.The results obtained for the two types of measurements show that through-space conjugation, due to overlap of the non-parallel ?-orbitals of the two aromatic systems, operated in both cis-systems.
