“…Ir(C 2 H 4 ) 2 (C 5 H 7 O 2 ) [7] [(acetylacetonato)-bis(g 2 -ethene)iridium(I)] is similarly a potential catalyst precursor, but the reported synthesis has, in our hands, been less than optimal, and there is no definitive report of its structure. Thus, we developed a new synthesis of Ir(C 2 H 4 ) 2 (C 5 H 7 O 2 ) and investigated its structure, by X-ray crystallography and IR, Raman, and NMR spectroscopies and calculations at the level of density functional theory (DFT).…”

“…The bis(ethene) complex [Ir(j 2 -acac)(C 2 H 4 ) 2 ] (1) reacts with tertiary phosphanes to give the monosubstitution products [Ir(j 2 -acac)(C 2 H 4 )(PR 3 )] (2±5). While 2 (R = iPr) is inert toward PiPr 3 , the reaction of 2 with diphenylacetylene affords the p-alkyne complex [Ir(j 2 -acac)(C 2 Ph 2 )-(PiPr 3 )] (6). Treatment of [IrCl(C 2 H 4 ) 4 ] with C-functionalized acetylacetonates yields the compounds [Ir(j 2 -acacR 1,2 )(C 2 H 4 ) 2 ] (8,9), which react with PiPr 3 to give [Ir(j 2 -acacR 1,2 )(C 2 H 4 )(PiPr 3 )] (10,11) by displacement of one ethene ligand.…”

“…Der Bis(ethen)-Komplex 1, der bei der Umsetzung von [IrCl(C 2 H 4 ) 4 ] und Kaliumacetylacetonat entsteht [6], reagiert nicht nur mit PiPr 3 [5] sondern auch mit PPh 3 und funktionalisierten Phosphanen PiPr 2 X (X = CH 2 CH 2 OMe, CH 2 CO 2 Me) unter Verdra Èngung eines Ethenliganden (Schema 1). Die Substitution verla È uft sehr rasch und liefert die Verbindungen 3±5 in Ausbeuten von 78±96%.…”
