Carbonyl-bis-{6,6'-[(3,3'-di--butyl-5,5'-dimeth-oxy-1,1'-biphenyl-2,2'-di-yl)bis(oxy)]bis-(dibenzo[,][1,3,2]-dioxaphosphepine)}hydridorhodium(I) toluene- 2.25-solvate.

The crystal-structure determination of the title compound, [RhH(CHOP)(CO)]·2.25CD, is reported. The bis-phosphite ligand, CHOP, is well known as Biphephos.

Iron-Catalyzed Alkoxycarbonylation of Alkyl Bromides via a Two-Electron Transfer Process.

Transition metal-catalyzed carbonylative cross-coupling reactions are some of the most widely used methods in organic synthesis. However, despite the obvious advantages of iron as an abundant and low toxicity transition metal catalyst, its practical application in carbonylation reaction remains largely unexplored. Here we report our recent study on Fe-catalyzed alkoxycarbonylation of alkyl halides.
