An efficient electrochemical method for benzylic C(sp3)-H bond oxidation has been developed. A variety of methylarenes, methylheteroarenes, and benzylic (hetero)methylenes could be converted into the desired aryl aldehydes and aryl ketones in moderate to excellent yields in an undivided cell, using O2 as the oxygen source and lutidinium perchlorate as an electrolyte. On the basis of cyclic voltammetry studies, 18O labeling experiments, and radical trapping experiments, a possible single-electron transfer mechanism has been proposed for the electrooxidation reaction.

A mild and selective C(sp3)?H aerobic oxidation enabled by decatungstate photocatalysis has been developed. The reaction can be significantly improved in a microflow reactor enabling the safe use of oxygen and enhanced irradiation of the reaction mixture. Our method allows for the oxidation of both activated and unactivated C?H bonds (30 examples). The ability to selectively oxidize natural scaffolds, such as (?)-ambroxide, pregnenolone acetate, (+)-sclareolide, and artemisinin, exemplifies the utility of this new method.
AN EFFICIENT FRIEDEL-CRAFTS SYNTHESIS OF 2-ACYLBENZOFURANS
Gill, Melvyn

2-(Trimethylsilyl)benzofuran, available quantitatively from benzofuran itself, reacts rapidly with primary, secondary, and tertiary aliphatic carboxylic acid chlorides in the presence of titanium(IV) chloride at low temperature to afford the corresponding 2-acylbenzofurans in excellent yields.This approach offers significant synthetic advantage over existing routes to the title compounds.
