Azobenzenes and heteroaromatic nitrogen cyclopalladated complexes for advanced applications

The Scope of Ambiphilic Acetate‐Assisted Cyclometallation with Half‐Sandwich Complexes of Iridium, Rhodium and Ruthenium

“…The presence of aromatic character in the ring has been proposed as a factor in the success of such reactions. [30] Thus, whilst cyclometallation with [{IrCl 2 Cp*} 2 ] is successful with a wide range of nitrogen donor ligands in the presence of NaOAc, steric effects, solvent and base all impact on the success of cyclometallation reactions with [{RhCl 2 Cp*} 2 ] and [{RuCl 2 …”

Curcumin and cyclopalladated complexes: A recipe for bifunctional biomaterials

“…Our experience in cyclopalladation for various applications [11] and most recently in ortho-palladation to produce antitumor agents [12] encouraged the design of a new cyclometallating ligand, 4-hexadecyloxycarboxylate-2-phenylquinoline, L (Scheme 1), to investigate its cyclopalladating ability through different approaches. Depending on the palladium source, stoichiometric ratio and synthetic pathway, the first examples of dinuclear bridged cyclopalladated derivatives have been obtained and structurally characterized.…”

“Rollover” cyclometalation – early history, recent developments, mechanistic insights and application aspects

“…in the field of supramolecular chemistry, [45][46][47][48][49][50][51][52] or as chemosensors, [53][54][55][56][57][58][59] switches, 60-62 metallomesogens [63][64][65][66][67][68] and also due to their photoluminescent and electronic properties, [69][70][71][72][73][74][75][76][77][78][79][80][81][82][83] no attempts will be made to include these aspects, even when related to ''rollover'' cyclometalated complexes, because the ''rollover'' cyclometalated ligands in these systems mostly act as mere spectators. In this review, the focus will be rather on the ''rollover'' process itself.…”
