Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 224311-51-7, Name is 2-(Di-tert-Butylphosphino)biphenyl. In a document type is Article, introducing its new discovery., 224311-51-7
Synthesis of Ni(II) Complexes Supported by Tetradentate Mixed-Donor Bis(amido)/Phosphine/Phosphido Ligands by Phosphine Substituent Elimination
A convenient nickel-templated phenyl elimination route is described for the synthesis of phosphide-containing multidentate ligands from triarylphosphine precursors. Treating Ni(COD)2 with the neutral bis(amine)/bis(phosphine) ligand precursor H2 4Ph[PNNP] affords bis(amido)/bis(phosphine) complex 1. Treatment of 1 with 1 equiv of KH leads to elimination of a phenyl group from one of the phosphine fragments, generating bis(amido)/phosphine/phosphido complex 3Ph[PNNP]Ni- (2). Alternatively, excess KH or nBuLi affords the bis(amido)/bis(phosphide) complex 2Ph[PNNP]Ni2- (3 or 4, respectively) by elimination of two phenyl substituents. These reactions are high-yielding and provide a unique and straightforward route to chelating phosphido ligands that would otherwise be challenging to synthesize.
224311-51-7, We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 224311-51-7, and how the biochemistry of the body works.
