Organometallic chemistry: synthesis and applications of cyclometallated compounds

Cyclometallated compounds are organometallic complexes which contain metallacycles with an E-M-C sequence of sigma bonds, where E is usually a 15 or 16 group donor atom, M is a metallic centre and C is a sp2 or sp3 carbon atom. Figure 1 shows the structural formula of some cyclometallated compounds containing d, p and f metallic centres. Different methods of preparation of cyclometallated compounds are known (cyclometallation, oxidative addition, transmetallation, transcyclometallation, expansion of the cyclometallated ring, external nucleophilic attack on a coordinated ligand), but the most interesting one is the cyclometallation reaction. This reaction consists in the intramolecular activation of a C-X sigma bond, where X is an atom of a non-metallic element, of a coordination compound and gives place to the formation of the M-C sigma bond of the metallacycle.

Cyclometallation reactions, which allow the activation of C-H, C-C or C-F bonds, are noteworthy since these bonds present a large energy of dissociation and therefore a very limited chemical reactivity. Figure 2 shows examples of C-H, C-C and C-F intramolecular activations. The intramolecular C-H activation reactions at Pd(II) and Pt(II) complexes have been extensively studied. In the case of Pd(II), the intramolecular C-H activation (cyclopalladation reaction) takes place by an agostic interaction and with the help of an internal base, usually an acetato ligand (Figure 3). This is called "the electrophilic mechanism". Platinum(II), in function of its coligands, can activate C-H bonds by the electrophilic mechanism or by an oxidative addition mechanism. Figure 3 gives examples of cyclo-palladation and -platination reactions, which take place through the electrophilic mechanism or by the oxidative addition mechanism.

The reactivity of the cyclometallated compounds of the platinum group metals has been extensively studied. These compounds have a reach reactivity and can react with Lewis bases (Figure 4), nucleophiles and electrophiles and experience oxidative addition, insertion and reductive elimination reactions. The reactivity of the sigma metal-carbon bond or that of the metallic centre of cylometallated compounds of the platinum group metals, especially those of Pd(II) and Pt(II), has allowed the preparation of new organic or organometallic compounds, such as those shown in Figure 5.

It should be noted that: i) the cyclometallation reaction has been used to introduce metal centres in organic dyes, dendrimers and mesogens, ii) the catalytic functionalization of C-H bonds in a very important number of organic molecules with an adequate directing group based on an intramolecular C-H bond activation, has been achieved using Fe(II), Ru(0), Ru(II), Co(I), Co(III), Rh(I), Rh(III), Ir(I), Ir(III), Ni(II) and Pd(II) compounds, among other transition metal compounds, as catalysts, and iii) some cyclometallated compounds of the platinum group metals are excellent catalysts for some organic reactions, such as the Heck and Suzuki reactions and the Aza-Claisen reaction in the case of those of Pd(II), among other organic reactions, and have been applied in optical resolution, in supramolecular chemistry, and in photophysics, in this latter case as sensors for molecules or ions, as catalysts for photoredox reactions, or as phosphors in OLEDs or in photovoltaic solar cells.

Finally, it is also worth of mention that recently an important number of articles of Pt(II), Pt(IV), Au(III), Ru(II), Pd(II) and Ir(III) cyclometallated compounds deal with their plausible applications in medicine and in biomedicine.
