Binuclear oxidative addition of Sb-Cl bonds : a facile synthetic route to main group transition element clusters and rings
Binuclear oxidative addition of Sb–Cl bonds with the clusters Os3(CO)11(NCCH3), 1, or Os3(CO)10(NCCH3)2, 2, was found to be an effective synthetic route to organometallic clusters and rings containing μ2-SbPh2 or μ3-SbPh ...
Synthesis and reactivity of cationic iridium aminocarbenes derived from terminal alkynes and 2-aminopyridines
The reaction of a terminal alkyne (RCCH) and 2- aminopyridine (R′C5NH3NH2) with the dinuclear species [Cp*IrCl2]2 afforded the cationic aminocarbene derivatives Cp*Ir(Cl)[ C- (CH2R)NHC5NH3R′] via a hydroamination and ...
Photochemical reaction of Cp*Ir(CO)2 with C6F5X (X = CN, F) : formation of diiridium(II) complexes
Visible light irradiation of Cp*Ir(CO)2 (1) in pentafluorobenzontrile resulted in the formation of the two isomeric diiridium(II) complexes [Cp*Ir(μ-CO)(C6F4CN)]2 (3) and [Cp*Ir(CO)(C6F4CN)]2 (4), while the analogous reaction ...
Oxidative addition across Sb–H and Sb–Sb bonds by an osmium carbonyl cluster : trapping the intermediate
The cluster Os3(CO)11(NCCH3) oxidatively adds across the Sb–H bond in SbPh2H to afford the clusters Os3(CO)11(H)(μ-SbPh2) and Os3(CO)11(μ-H)(μ-SbPh2)Os3(CO)11. Similarly, its reaction with Sb2Ph4 afforded Os3(CO)11(μ-SbP ...
Synthesis and Reactivity of Ruthenium-Antimony Carbonyl Clusters
The reaction of Na[HRu3(CO)11] (2) with SbPh2Cl in dry tetrahydrofuran (THF) afforded the cluster Ru3(CO)10(μ-H)(μ-SbPh2) (3); in dry dichloromethane (DCM), the six-membered ring Ru6(CO)20(μ-H)2(μ-SbPh2)2 (4) was obtained ...
