A new convenient method for the high-yield synthesis of Ir4(CO)12

Aminoethyl‐Functionalized Cyclopentadienyliridium Complexes: Photochemical C–H Activation and Carbonylation of Cycloalkanes

“…We confirmed the identity of 4 by an independent synthesis,9 and also found that upon irradiation, a degassed suspension of 4 in cyclohexane in the presence of Cp*H or Cp*H gave partial conversion to 1b or 1d , respectively, as identified by IR spectroscopy. Further irradiation of the reaction mixture containing 1b and the starting materials resulted in the formation of the corresponding hydridoalkyl species 2b ; the yield of 2d for the corresponding reaction was low.…”

An Unusual Carbonyl Chemical Shift in a Carbonylhexairidium Cluster: A Combined Solid‐State NMR and DFT Approach

“…[Ir(CO) 4 ] -, [16] [Ir 4 (CO) 12 ], [17] [Ir 6 (CO) 15 ] 2-, [18] and [Ir 6 (CO) 16 ] [19] were prepared according to the published methods; IR spectra were recorded with a Bruker Vector 22 FT-IR spectrophotometer, using 0.1 mm CaF 2 cells previously purged with N 2 .…”

The Surface of Inorganic Oxides or Zeolites as a Nonconventional Reaction Medium for the Selective Synthesis of Metal Carbonyl Complexes and Clusters

“…These silica-mediated syntheses represent an alternative to traditional methods in solution. 33,34 32 The silica-mediated synthesis of K 2 [Ir 6 (CO) 15 ] is comparable to the traditional one in solution 36 whereas the silica-mediated route to [Ir 8 (CO) 22 ] 2is much more attractive (better yields, more convenient starting material) than the synthesis in solution. 37,38 Interestingly, on the silica surface the use of high temperatures (150-200 °C) leads to a new anionic high-nuclearity iridium carbonyl cluster which had never been observed when working in solution.…”
