Cyclometallated complexes of Pd(II) with heterobidentate P, As and P, N coordinating ligands

Synthesis, structure, catalytic transfer hydrogenation and biological activity of cyclometallated ruthenium(III)2-(arylazo)phenolate complexes

“…The potentials are summarized in Table 5 Fig. 3. EPR spectrum of the complex 7 in dichloromethane solution at 77 K. and a representative voltammogram is shown in Fig.…”

“…The cyclometallation reaction, i.e., the intramolecular activation of aromatic C-H bonds of coordinated ligands by transition metals has been widely studied [1][2][3][4][5]. Conventionally cyclometallation has involved one ligating group holding a metal center close to C-H bond and subsequent closure of the ring via the formation of carbon to metal bond [6,7].…”

Synthesis, characterization and crystal structures of cyclometallated palladium (II) compounds containing difunctional ligands with [P,P], [As,As], [N,N], [P,As], [P,N] and [P,O] donor atoms

“…Suitable crystals were grown by slowly evaporating chloroform/ n-hexane (1, 5, 15, 16) or dichloromethane/n-hexane (18,20) solutions of the complexes.…”

“…We were now interested in looking further into the chemistry of cyclopalladated complexes when they react with other bidentate group 15 donor atom ligands such as diamines. Furthermore, there has been recent interest in the chemistry of polydentate ligands, especially those which combine ''soft" and ''hard" donor atoms [11][12][13][14][15][16][17][18]. These ligands show a characteristic behaviour when binding to soft metal centers giving complexes that are good catalysts in numerous processes [19][20][21][22][23].…”

Synthesis and structure of cycloruthenated carbonyl complexes and their emission, redox and biological properties

“…Conventionally, cyclometallation/orthometallation has involved one ligating group holding a metal center close to C-H bond and subsequent closure of the ring via the formation of carbon to metal bond [1][2][3][4]. Since the first cyclometallated complex was synthesized, cyclometallation has become an important part of organometallic chemistry.…”
