A new coupling partner: Vinylacetate couples with organoboroncompounds in the presence of a rhodium catalyst; carbon–carbon bond formation occurs on the vinylic carbon attached to the acetoxy group. Conventional nickel and palladium catalysts were found to be ineffective for the reaction.

bond-forming reductive coupling of nitroalkanes with arylboronicacids and esters is reported. The method shows excellent chemoselectivity for the nitro/boronicacid substrate pair, allowing the synthesis of N-(hetero)arylamines rich in functionalization. The identification of a sterically reduced phosphetane catalyst capable of productive coupling in the P(III)/P(V)═O redox manifold is the key enabling development
