On the regioselectivity of coupling of substituted allyl radicals. Steric versus FMO control
摘要:
The photo-induced decomposition of substituted-homoallylic 4-nitrobenzenesulfenates produces substituted allyl radicals which undergo dimerization and coupling with the 4-nitrobenzenethiyl radical. The regioselectivity of the dimerization of the allyl radicals is controlled by both steric and FMO properties depending on the nature of the substituent.
