Gao, Hui published the artcileElectrochemical benzylic C-H arylation of xanthenes and thioxanthenes without a catalyst and oxidant, Formula: C8H10O2, the publication is Organic Chemistry Frontiers (2022), 9(7), 1911-1916, database is CAplus.
A catalyst-free and oxidant-free C-H arylation of xanthenes and thioxanthenes I (R1 = H, Me, OH, Cl, etc.; R2 = H, OMe; R3R4 = -CH=CH-CH=CH-; X = O, S) using electrochem. has been developed, which affords a number of cross-coupling products II (R5 = 4-methoxyphenyl, 4-methoxy-3-methylphenyl, 4-methoxy-3,5-dimethylphenyl, 2H-1,3-benzodioxol-5-yl, etc.) in moderate to good yields. This method is atom- and step-economical as it uses cheap and easily available arenes and heteroarenes as partners directly and the C(sp2)-H/C(sp3)-H type cross-coupling reaction.
