Ir(III)-catalyzed C−H alkylation of BINOL units has been well examined by allyl alcohols as coupling partners. Under the advantage of pyridine guiding group, the efficient protocol allows the rapid synthesis...

A novel C–H acyloxylation method of 1-(1-naphthalen-1-yl)­isoquinoline derivatives with peresters in the presence of [Ru­(p-cymene)­Cl2]2 has been developed. The combination of ruthenium­(II), AgBF4, CoI2, and 2,2,6,6-tetramethyl-1-piperidinyloxy is found to be an effective catalytic system to provide various biaryl compounds in satisfactory yields within minutes. Notably, steric hindrance is a very important determinant of the reaction.

A highly efficient Rhodium(III)‐catalyzed annulative coupling was developed for generating bicyclo[4.1.0] heptan‐2‐ones from sulfoxonium ylides and allyl acetates under mild conditions. This cascade reaction is versatile to construct cyclopropanes, and the starting materials are stable and easily obtainable.
