A simple and practical manganese(iii)-promoted tandem phosphinoylation/cyclization of 2-arylindoles/2-arylbenzimidazoles with disubstituted phosphine oxides was developed.

A new, practical directed anodic C–H sulfonylation of N,N-disubstituted anilines with sodium sulfinates for producing o- or p-amino arylsulfones and diarylsulfones is described.

A highly para-selective amination of anilines with phenothiazines for producing various functionalized 10-aryl-10H-phenothiazines is reported.

A simple protocol for the three-component intermolecular alkylesterification of styrenes with toluenes and peroxyesters using a copper catalyst is described. A variety of ester-containing complex compounds were synthesized with excellent functional group tolerance and step efficiency. Employing the combination of carboxylic acids and di-tert-butyl peroxide (DTBP) oxidant instead of peroxyesters also gave similar results. In this transformation, aromatic acids, aliphatic acids, and amino acids were suitable substrates.

A copper and silver‐promoted intermolecular 1,2‐alkylarylation of styrenes with α‐carbonyl alkyl bromides and arenes for producing highly bulky 1,1‐diarylalkane derivatives has been developed. In this transformations, two new C−C bonds were formed in a single reaction step through C−Br bond cleavage and C(sp2)−H functionalization. This protocol tolerates a variety of α‐carbonyl alkyl bromides, including primary, secondary and tertiary α‐bromoalkyl ketone esters.magnified image

A new silver-mediated 1,2-alkylesterification of alkenes with nitriles and acids promoted by a catalytic amount of nickel catalyst for producing acyloxylated nitriles has been developed via a C(sp3)–H functionalization process.
