ChemInform Abstract
Electron transfer chain reactions leading to substitution in electronegatively substituted benzene derivatives can be observed with alkylmercury halides in the presence of proton acceptors such as DABCO. Such processes occur in the photolysis of tBuHg-halides with benzaldehyde, phenones, phthalimides and other disubstituted benzenes as well as in the homolytic cyclization to α-tetralone. A mechanism involving radical adducts and radical anions is discussed.
