Webb18 nov. 2009 · A novel palladium-catalyzed intramolecular oxidative aminofluorination of unactivated alkenes has been developed, in which AgF was used as a key fluorinating reagent and PhI (OPiv) (2) as oxidant. The reaction afforded vicinal fluoroamine products with very high regioselectivity. A Pd (II/IV) catalytic cycle was proposed, and preliminary ... Webb1 feb. 2024 · It was found that, changing the solvent from nitromethane to 1,2-dichloroethane, was beneficial for the reaction outcome. Specifically, when PhI(OPiv) 2 was employed as oxidant, both 1a and 1b could be efficiently converted into the desired products 3a and 3b in 86 and 80% yields, respectively (Table 2, entries 1 and 2). WebbA mild, metal-free synthesis of pyrido[1,2-a]benzimidazoles starting with N-benzyl-2-aminopyridines, which employs PhI(OPiv) 2 as a stoichiometric oxidant, has been developed. The process is initiated by an unusual PhI(OPiv) 2-mediated ipso S E Ar reaction, followed by solvent-assisted C-C and C-N bond cleavage. View More grand haven michigan police department
