Na[cyclo-(P(5)(t)Bu(4))] (1) reacts with [RhCl(PPh(3))(3)] (1:1) to give the first rhodium(I) complex with a tetra-tert-butylcyclopentaphosphanide ligand, [Rh{cyclo-(P(5)(t)Bu(4))}(PPh(3))(2)] (2). 2 was characterized by NMR ((1)H, (13)C, (31)P), MS, IR, and X-ray structure determination.

Ring strain governs transmetalation behaviour at a tucked-in iron complex.

Studies that independently investigate [M]-C transmetalation reactions using two different metals are uncommon and yet understanding this reactivity is important to unlocking new synthetic approaches and product classes. Here, we show that the strained [Fe]-C complex, [(η-CMe-CH)Fe(diphosphine)] undergoes transmetalation with rhodium(I) and iridium(I) diolefin salts, leading to rapid Fe-C(sp) bond cleavage and M-C(sp) (M = Rh or Ir) bond generation.

Stable neutral metal radicaloid complexes have been synthesized from a modified tetrapyrrolic pigment, bilatriene, with iridium(I) and rhodium(I) cyclooctadiene (COD) synthons. The bilatriene skeleton contains α-linked conjugated pyrrole units, whereas an N-confused analogue used in this work possesses β-linked pyrrole moieties at the terminal, demonstrating a unique metal binding capability. Unprecedentedly, the metal-COD cations are accommodated at the outer nitrogen sites, which induced the formation of open-shell metal-radicaloid species.

This publication describes monodentate phosphine and oxazoline ligands attached to an amino acid ester and the application of their supramolecularly assembled rhodium(I) or iridium(I) complexes in asymmetric catalysis. The major feature of these complexes is the transmission of chirality from distant hydrogen bonded amino acids to the prochiral catalytic metal center ("backdoor induction"). The generated homoleptic and heteroleptic rhodium(I) or iridium(I) precatalysts were studied by NMR, UV-VIS and CD spectroscopy as well as X-ray single crystal diffraction.

The rare observation of transient Rh···Rh excimer formation in a single crystal is reported. The estimated excited-state lifetime at 100 K is 2 ns, which makes it the shortest-lived small-molecule species caught experimentally using the laser-pump/X-ray-probe time-resolved Laue method. Upon excitation with 390 nm laser light, the intermolecular Rh···Rh distance decreases from 3.

Homotrinuclear complexes of the -symmetric tris(ferrocenyl)arene-based tris-phosphanes 1a-d with ruthenium(ii) ([1a-d(Ru)]) and rhodium(i) ([1a-d(Rh)]) were prepared and fully characterised. Complexes [1a-d(Ru)] and [1a-d(Rh)] are electrochemically active. The nature of the arene core in 1a-d ranging from benzene, 1,3,5-trifluorobenzene and mesitylene to -triazine allows to fine-tune the exact oxidation potentials for tailoring the electrochemical response.
