[Cp*Ir(H2O)3][OTf]2, a variety of aldoximes, including aromatic, aliphatic, conjugatedunsaturated and non-conjugated unsaturated, were converted into their corresponding amides in water with good to excellent yields. Further, the one-pot synthesis of amides from aldehydes, hydroxylamine hydrochloride and sodium carbonate via a tandem condensation–rearrangement reaction in water was also accomplished. Compared

The functionalized NHC obtained from salt 2 is a good ligand for palladium in the Heck–Matsudareaction of arenediazonium salts and different alkenes. The reaction is performed with low catalyst loading (0.5–1 mol-% of Pd) and in the absence of a base for acrylates. The protocol is also useful for the preparation of cinnamide derivatives. Compound U-77863 has been prepared successfully in good isolated
