Bis(cyclopentadienyl)methane-bridged dinuclear complexes. IV. Synthesis, structure, and reactivity of dinuclear rhodium and iridium complexes in the oxidation state +I and +III with the bis(cyclopentadienyl)methane dianion as bridging ligand was written by Werner, Helmut;Treiber, Monja;Nessel, Angelika;Lippert, Ferdinand;Betz, Peter;Krueger, Carl. And the article was included in Chemische Berichte in 1992.Recommanded Product: 39722-81-1 This article mentions the following:
The rhodium compounds [CH2(C5H4)2][Rh(L)(C2H4)]2 [L = CO, P(CHMe2)3 (PiPr3) (I)] were prepared from [RhCl(L)(C2H4)]2 and CH2(C5H4)2Li2 in 92 and 73% yield, resp. The reaction of I (L = PiPr) with X2 (Cl2, Br2, and I2) led to the almost quant. formation of the dihalo derivatives [CH2(C5H4)2][RhX2(PiPr3)]2 (II), which on treatment with excess NaBH4 and methanol gave the dihydride [CH2(C5H4)2][RhH2(PiPr3)]2 (III). From [RhCl(C8H14)2]2, PiPr3, and CH2(C5H5)2 [CH2(C5H4)2][RhH(Cl)(PiPr3)2 was obtained. Protonation of III with CF3CO2H in the presence of NH4PF6 gave the PF6 salt of the hydrido-bridged cation {[CH2(C5H4)2][RhH(PiPr3)]2(μ-H)}+ of which the crystal structure was determined In solution, fluxional behavior of the cation was observed The di-Me compound [CH2(C5H4)2][Rh(CH3)2(PiPr3)]2 prepared from II and LiCH3 or CH3MgI in 80% yield, reacted with CF3CO2H at -78° to give the trifluoroacetato derivative IV; this on treatment with P(OMe)3 and dmpe formed dicationic complexes. The dinuclear iridium compounds [CH2(C5H4)2][Ir(olefin)2]2 and [CH2(C5H4)2][Ir(C8H12)]2 were prepared from [IrCl(L)2]2 and CH2(C5H4)2Li2 and used for the synthesis of {[CH2(C5H4)2][IrX2]2}n. V (X = Br, iodo) served as starting materials for the preparation of the dinuclear derivatives [CH2(C5H4)2][IrX2(L)]2 and {[CH2(C5H4)2][IrBr2]2(μ-dipy)} and finally also for the dihydrido complex [CH2(C5H4)2][IrH2(PiPr3)]2. In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Recommanded Product: 39722-81-1).
Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Recommanded Product: 39722-81-1
