“…observed regioselectivity is consistent with literature for related substituted N,O-bidentate ligands [7,8]. Phosphine modified ligands in heterobimetallic complexes of ferrocene and rhodium have been reported to show improved catalytic activity compared to their mononuclear counterparts in the hydroformylation of olefins [19,20]. The heterobimetallic catalyst precursors bearing N,O-bidentate ligands in this study showed diminished activity in comparison to previous studies.…”

“…Ferrocene, a redoxactive sandwich complex, has been included in several heterobimetallic complexes in combination with other transition metals, bridged by various ligand structures. In this context, the inclusion of ferrocene moieties modified with phosphorus donor sites is very common [16,19,20].…”

Monometallic and heterobimetallic complexes of Rh(I) bearing chelating N,O‐bidentate aryl‐ and ferrocenyl‐derived ligands have been synthesised via Schiff base condensation reactions, and characterised fully using 1H NMR, 13C{1H} NMR and Fourier transform infrared spectroscopies, elemental analysis and mass spectrometry. The new monometallic and heterobimetallic complexes were evaluated as potential catalyst precursors in the hydroformylation of 1‐octene at 95°C and 40 bar. The ferrocenylimine mononuclear compounds were inactive in the hydroformylation experiments. The Rh(I) monometallic and the ferrocene–Rh(I) heterobimetallic pre‐catalysts displayed good activity and conversion of 1‐octene as well as outstanding chemoselectivity towards aldehydes in the hydroformylation reaction.

A series of rhodium(I)-1,2,3-triazol-5-ylidene (trz) complexes are described, containing either a novel triarylated trz ligand A′ (N1, N3-arylated, C4-ferrocenyl) {complexes 1, [Rh(A′)Cl(cod)]; 4, [Rh(A′)Cl(CO) 2 ]}, or N3-alkylated triazolylidenes with a C4-ferrocenyl {2, [Rh(B′)Cl(cod)]; 5, [Rh(B′)Cl(CO) 2 ]} or C4-phenyl substituent {3, [Rh(C′)Cl(cod)]; 6, [Rh(C′)Cl(CO) 2 ]}. The free mesoionic carbene (MIC) A′ is structurally characterized and its electronic properties evaluated by employing the [a] 1227 Scheme 1. Synthesis of tri -(1, 4) and diarylated (2, 3, 5 and 6) triazolylidene-Rh I complexes.Scheme 2. Synthesis of free carbene A′ and Pd II complex 7. Crystal Structure Determination: Single crystal X-ray diffraction data for A, A ox , 1, 2 and 4 were collected with a Bruker Apex II-CCD detector using Mo-K α radiation (λ = 0.71073 Å), while for A′ Eur.
