Suzuki-Miyaura cross-couplings of amides offer an approach to the synthesis of ketones that avoids the use of basic or pyrophoric nucleophiles. However, these reactions require glovebox manipulations, thus limiting their practicality. We report a benchtop protocol for Suzuki-Miyaura cross-couplings of aliphaticamides that utilizes a paraffin capsule containing a Ni(0) precatalyst and NHC ligand. This

amide-based substrate and the boronate coupling partner and proceeds in the presence of heterocycles and epimerizable stereocenters. Moreover, a gram-scale Suzuki–Miyauracoupling/Fischer indolization sequence demonstrates the ease with which unique polyheterocyclic scaffolds can be constructed, particularly by taking advantage of the enolizable ketone functionality present in the cross-coupled product. The

A metal-free protocol for the coupling reaction of aldehydes and alkyl halides was successfully developed with mesoionic carbenes (MICs) as catalysts. This versatile strategy delivers a large diversity of simple ketones as well as bio-active molecules by late-stage functionalization.
