Ketyl-initiated reaction between Ru3(CO)12 and phenyldi(2-thienyl)phosphine (PhPTh2) furnished simple phosphine-substituted triruthenium clusters [Ru3(CO)10(PhPTh2)21 and [Ru3(CO)9(PhPTh2)3] 2. Heating 1 in boiling benzene afforded [Ru3(CO)8{?3- PhThP(C4H2S)}(PhPTh2)] 3 by carbon-hydrogen bond cleavage of a coordinated thienylphosphine ligand. All three new clusters have been characterized by elemental analysis, IR and NMR spectroscopic data.DOI: http://dx.doi.org/10.3329/jbcs.v25i1.11764 Journal of Bangladesh Chemical Society, Vol. 25(1), 1-6, 2012

Organoplatinum Compounds

We report selective formation of heterobimetallic PtII/CuI complexes that demonstrate how facile bond activation processes can be achieved by altering reactivity of common organoplatinum compounds through their interaction with another metal center. The interaction of the Cu center with Pt center and with a Pt-bound alkyl group increases the stability of PtMe2 towards undesired rollover cyclometalation. The presence of the CuI center also enables facile transmetalation from electron-deficient tetraarylborate [B(ArF)4]- anion and mild C-H bond cleavage of a terminal alkyne, which was not observed in the absence of an electrophilic Cu center. The DFT study indicates that the role of Cu center acts as a binding site for alkyne substrate, while activating its terminal C-H bond.

Reactions of cyclometalated compounds are numerous. This account is focused on one of such reactions, the exchange of cyclometalated ligands, a reaction between a cyclometalated compound and an incoming ligand that replaces a previously cyclometalated ligand to form a new metalacycle: + H-C*~Z ⇄ + H-C~Y. Originally discovered for PdII complexes with Y/Z = N, P, S, the exchange appeared to be a mechanistically challenging, simple, and convenient routine for the synthesis of cyclopalladated complexes. Over four decades it was expanded to cyclometalated derivatives of platinum, ruthenium, manganese, rhodium, and iridium. The exchange, which is also questionably referred to as transcyclometalation, offers attractive synthetic possibilities and assists in disclosing key mechanistic pathways associated with the C–H bond activation by transition metal complexes and C–M bond cleavage. Both synthetic and mechanistic aspects of the exchange are reviewed and discussed.
