Metal-Assisted Cleavage of a C-O Bond of a P-Bound Bifunctional Phosphine Ligand was written by Steinert, Paul;Werner, Helmut. And the article was included in Organometallics in 1994.Synthetic Route of C8H16Cl2Ir2 This article mentions the following:
Treatment of [IrCl(C2H4)2]2 with the phosphino ester iPr2PCH2CO2Me affords the mononuclear complex trans-[IrCl(C2H4)(iPr2PCH2CO2Me-魏P)2], which reacts with CO to give trans-[IrCl(CO)(iPr2PCH2CO2Me-魏P)2] (I) and with HC顚咰R to give [IrH(C顚咰R)Cl(iPr2PCH2CO2Me-魏P)(iPr2PCH2CO2Me-魏3P,O)] (R = Ph, CO2Me). Upon heating, these alkynylhydridoiridium compounds rearrange to yield the isomeric vinylidenemetal derivatives trans-[IrCl(:C:CHR)(iPr2PCH2CO2Me-魏P2)] (II, R = Ph, CO2Me). Reaction of I or II with Al2O3/H2O leads to cleavage of a CH3-O bond of one phosphino ester ligand and gives the iridium chelate complexes [Ir(L)(iPr2PCH2CO2Me-魏P)(iPr2PCH2CO2-魏3P,O)] (III, L = CO, C:CHPh, C:CHCO2Me) in 80-90% yield. III (L = CO) reacts with Me iodide by oxidative addition to form the octahedral complex [IrI(CH3)(CO)(iPr2PCH2CO2Me-魏P)(iPr2PCH2CO2-魏2P,O)]. The X-ray crystal structure of III (L = CO) has been determined In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Synthetic Route of C8H16Cl2Ir2).
Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Synthetic Route of C8H16Cl2Ir2
