    • In this context, electrophilic metals imply a larger charge transfer from the C-H bond to the metal, whereas nucleophilic centres engage in larger backbonding, i.e. charge transfer from the metal to the C-H σ* orbital. In amphiphilic centres bonding and backbonding are nearly balanced. See

    • In earlier work (ref. 17), only complex 5 was isolated after column chromatography as this was the expected product (cf. ref. 19a) and hence purification was not further pursued. Diligent analysis of the reaction mixture in further experiments revealed the formation of two more products, viz. 4 and 6, as reported here

    • Exclusive arrangement of the iodide ligand cis to the alkyl ligand is in agreement with the a significantly different trans influence of the normal NHC and the alkyl ligand. Notably, this difference is considerably smaller between abnormal NHC and the alkyl group, cf. NMR spectroscopic data of 2 and 4

    • This conclusion is further supported by separate experiments involving the exposure of pure complex or 6 to the reaction conditions used for their preparation (KI, NaOAc, MeCN, reflux for several hours). In either case, the complexes were stable and did not show any detectable interconversion to the other complex
