The C–C triple bond of phenylacetylene undergoes the anti-Markovnikov addition of the Rh–H bond of RhH{κ3-P,O,P-[xant(PiPr2)2]} (1; xant(PiPr2)2 = 9,9-dimethyl-4,5-bis(diisopropylphosphino)xanthene) to give Rh{(E)–CHCHPh}{κ3-P,O,P-[xant(PiPr2)2]} (2), which reacts with a second alkyne molecule to produce Rh(CCPh){κ3-P,O,P-[xant(PiPr2)2]} (3) and styrene before the transformation from 1 to 2 is complete. The metal center of 3 undergoes the oxidative addition of the C(sp)–H bond of another alkyne molecule to produce RhH(CCPh)2{κ3-P,O,P-[xant(PiPr2)2]} (4), which also reacts with more phenylacetylene before completing the transformation from 3 to 4. The reaction leads to Rh{(E)–CHCHPh}(CCPh)2{κ3-P,O,P-[xant(PiPr2)2]} (5), which reductively eliminates (E)-1,4-diphenyl-1-buten-3-yne to regenerate 3. Complexes 3, 4, and 5 constitute a cycle for head-to-head dimerization of phenylacetylene. Consequently, complex 1 promotes the catalytic homocoupling of terminal alkynes to (E)-enynes, including the dimerization of α-hydroxyacetylenes to (E)-enyne-diols. The rate-determining step of the couplings depends on the nature of the alkyne, being the insertion of the C–C triple bond into the Rh–H bond of a bis(acetylide)-rhodium(III)-hydride intermediate for phenylacetylenes and the reductive elimination of the product (E)-enyne-diol for α-hydroxyacetylenes. In support of the latter, complex Rh{(E)–CHCHC(OH)Ph2}{CCC(OH)Ph2}2{κ3-P,O,P-[xant(PiPr2)2]} (6) has been isolated and characterized by X-ray diffraction analysis. Complex 1 also effectively promotes the formation of compounds of the type (E)-5-phenyl-2-penten-4-yn-1-ol, by cross-coupling between phenylacetylenes and α-hydroxyacetylenes. These reactions take place through two cycles similar to the cycle that produces the homocouplings, the rate-determining step being the reductive elimination of (E)-enyn-ol for both. The catalytic performance of 1 provides good efficiency in homocoupling and cross-coupling reactions involving progestin-type compounds such as ethisterone.

The rhodium and iridium complexes [Cp*M(κ3N,N′,N″-L)]SbF6 exhibit three different cooperative metal–ligand reactivity modes when interacting with nonfunctionalized ketones. With the methyl ketones CH3COR (R = CH3, Ph, CF3), activation of the ketone methyl C(sp3)–H bond yields ketonyl compounds of formula [Cp*M(CH2COR)(κ2N,N′-HL)][SbF6]. With the ketones (CF3)2CO and CF3COPh, the complexes add to the CO double bond of the ketone. The addition of the iridium compound 2 occurs across the metal atom and the exocyclic carbon of the dearomatized pyridinyl moiety, and that of the rhodium analogue 1 takes place through the rhodium atom and the exocyclic methylene carbon of the Cp* ligand of the intermediate fulvene complex. In the rhodium case, the resulting metal-alkoxide derivative evolves to give rise to rhodium derivatives containing up to four added ketone molecules. In all of these processes, no additives are required, rendering them atom 100% efficient procedures for bond activation. From a mechanistic point of view, DFT calculation reveals that the diverse and selective behavior of 1 and 2 toward ketones can be explained by invoking three different intermediates, each driving the process through distinct reaction pathways.

ConspectusChemical research in synthesizing metal nanoparticles has been a major topic in the last two decades, as nanoparticles can be of great interest in many fields such as biology, catalysis, and nanotechnology. However, as their chemical and physical properties are size-dependent, the reliable preparation of nanoparticles at a molecular level is highly desirable. Despite the remarkable advances in recent years in the preparation of thiolate- or p-MBA or PA-protected gold and silver nanoclusters (p-MBA = p-mercaptobenzoic acid; PA = phenylalkynyl), as well as the large palladium clusters protected by carbonyl and phosphine ligands that initially dominated the field, the synthesis of monodispersed and atomically precise nanoparticles still represents a great challenge for chemists.Carbonyl cluster compounds of high nuclearity have become more and more part of a niche chemistry, probably owing to their handling issues and expensive synthesis. However, even in large size, they are known at a molecular level and therefore can play a relevant role in understanding the structures of nanoparticles in general. For instance the icosahedral pattern, proper of large gold nanoparticles, is also found in some Au–Fe carbonyl cluster compounds.Rh clusters in general can also be employed as precursors in homo- and heterogeneous catalysis, and the possibility of doping them with other elements at the molecular level is an important additional feature. The fact that they can be obtained as large crystalline species, with dimensions of about 2 nm, allows one to place them not only in the nanometric regime, but also in the ultrafine-metal-nanoparticle category, which lately has been attracting growing attention. In fact, such small nanoparticles possess an even higher density of active catalytic sites than their larger (up to 100 nm) equivalents, hence enhancing atom efficiency and reducing the cost of precious-metal catalysts. Finally, the clusters’ well-defined morphology could, in principle, contribute to expand the studies on the shape effects of nanocatalysts.In this Account, we want to provide the scientific community with some insights on the preparation of rhodium-containing carbonyl compounds of increasing nuclearity. Among them, we present the synthesis and molecular structures of two new heterometallic nanoclusters, namely, [Rh23Ge3(CO)41]5– and [Rh16Au6(CO)36]6–, which have been obtained by reacting a rhodium-cluster precursor with Ge(II) and Au(III) salts. The growth of such clusters is induced by redox mechanisms, which allow going from mononuclear complexes up to clusters with over 20 metal atoms, thus entering the nanosized regime.
