derivatives into N-methylamines was developed using methanol as the C1 source via the one-pot Curtius rearrangement and borrowing hydrogen methodology. Following this protocol, various functionalised N-methylated amines were synthesized using the (NNN)Ru(II) complex from carboxylic acids via an acyl azide intermediate. Several kinetic studies and DFT calculations were carried out to support the mechanism

A concise synthesis of quinolinium, and biquinolinium salts and biquinolines from benzylic azides and alkenes promoted by copper(<scp>ii</scp>) species
copper-promoted cycloaddition reaction also allows biquinoline products to be obtained from ortho-substituted benzylic azides. These reactions work well with both terminal and internal alkenes. Unsymmetrical internal alkene reactions proceed with high regioselectivity. The reaction is likely started by Lewis acidic CuII-assisted rearrangement of benzylic azide to N-methyleneaniline, followed by a [4 + 2] cycloaddition

without any directing group by cross-dehydrogenative coupling between unactivatedC(sp3)–H and C(sp3)–Hbonds has been established for the first time, which provides a good complement to C(sp3)–Hactivation reactions and expands the field of Fe-catalyzed C–H functionalizations. Many different C(sp3)–Hbonds in cyclic alkanes, cyclic ethers, and toluene derivatives can be used as coupling partners. Mechanistic

A silver-catalyzed sequential formation of two C–C bonds for the construction of a series of polysubstituted quinolines from anilines, aldehydes, and alcohols under mild conditions has been developed. The transformation is effective for a broad range of substrates, including aliphatic alcohols, arylalkanols, cycloalkanols, and ethylene glycol, thereby permitting the expansion of the constituent architectures
