Photocatalyst-free visible-light-mediated C–H arylation of ethers via C(Sp2)–C(Sp3) C–H functionalization involving hydrogen atom transfer (HAT) pathway.
good yields and the complete selectivity obtained are due to the nucleophiliccharacter of the α-oxyalkyl radicals. A quantitative study concerning the nucleophiliccharacter of the dioxanyl radical, carried out by measuring the relative rates of attack on 4-substituted quinolines; revealed in detail all the features of nucleophilic substitutions.
