The Photolysis of Iodoaromatic Compounds

Abstract

Phenyl and aryl substituents considerably extend the charge delocalization of the transition state. In compounds with phenyl substituents on both C-3 and nitrogen [e.g. (14) and (9) Li, D, Cl, or Br are noted.

Radical grafting of carbon surfaces by oxidation of 5-nitroindole derived anions

“…Taking as an approximation the theoretical coverage factor for ferrocene molecules considered as spherical and packed in a compact hexagonal arrangement (C the = 4.5 Â 10 À10 mol cm À2 ) [49], the value of C exp /C the % 8 indicates formation of multilayers, which from the chemical point of view, could be produced by radical attack to the aromatic nucleus and hydrogen atom abstraction [50].…”

Organocatalytic C–H activation reactions

“…Transition-metal-catalyzed biaryl synthesis from unactivated arenes by C–H activation is well-known in the literature [26–30]. Stoichiometric amounts of a radical source, such as tributyltin hydride and tris(trimethylsilyl)silicon hydride [31], or irradiation [32] were also utilized for biaryl synthesis from unactivated arenes. However, organocatalysts have not been studied for this class of transformation.…”

Studies on enamides. Part-7: a novel photochemical reaction pathway of N-aroyl-N-1-cyclohexenylanilines

“…The photochemical reaction of enamides, apparently as first demonstrated by Eschenmoser et al 2 has been extensively utilized for the synthesis 3 of complex heterocycles, alkaloids and azasteroids. In connection with our interest for the photochemical studies on enamides [4][5][6][7][8] and other heterocyclic systems 9 , we envisaged to synthesize the hexahydrophenanthridones (6…”
