Cyclometallated iridium NHC complexes containing self-isomerised ligands as catalysts for hydrosilylation and transfer hydrogenation reactions Estefan van Vuuren, Frederick Pieter Malan and Marilé Landman Abstract Novel Ir-based NHC complexes (1-4) were synthesised using N-alkenyl functionalised imidazolium salts with Ir(III) precursors.

Self-Isomerized-Cyclometalated Rhodium NHC Complexes as Active Catalysts in the Hydrosilylation of Internal Alkynes

| ACS Publications
A range of unique Rh-based bidentate NHC complexes that are formed in a base-free tandem isomerization/cyclometalation process were synthesized (1–4) from a range of imidazolium salts with an N-alkenyl tether. Cyclometalation occurred with complex 1, leading to an unprecedented complex, which is the first and only example in the literature of a nonaromatic C(sp2)–H activation leading to a C(sp3)–Rh cyclometalated product with a concomitant intramolecular/isomerization process.
