resulting lithiated compounds with carbon dioxide (n = 2-7), benzaldehyde (n = 2-6), benzophenone (n = 2, 3), dimethylformamide (n = 2), ethyl formate (n = 2), and chlorodiphenylphosphine (n = 3) afforded the corresponding ortho-substituted hydroxyalkoxybenzenes in yields ranging from 45 to 83%. The synthesis is also reported of five new bis[o-(omega-hydroxyalkoxy)phenyl]mercurycompounds (n = 2-6), four

We report highly selective photocatalytic functionalisations of alkyl groups in arylalkylethers with a range of electron-poor alkenes using an acridinium catalyst with a phosphate base and irradiation with visible light (456 nm or 390 nm). Experiments indicate that the reaction operates via direct single-electron oxidation of the arene substrate ArOCHRR′ to its radical cation by the excited state
