Bis(diphenylphosphino)methane 97%; CAS Number: 2071-20-7; EC Number: 218-194-2; Synonyms: DPPM,Methanediylbis[diphenylphosphine,Tetraphenylmethylenediphosphine,DPM,Methylenebis(diphenylphosphine); Linear Formula: (C6H5)2PCH2P(C6H5)2 at Sigma-Aldrich

2021年8月24日 · The bis(diphenylphosphino)methane (DPPM) functionalized amidinate ligand was obtained by a two-step synthesis route on a multigram scale (Scheme 1). First, DPPM was reacted with n-BuLi, leading to deprotonation of the methylene moiety.

2020年10月15日 · Review on bimetallic complexes bearing dppm as bridging ligand. Comparisons on anti-cancer activities. Synthesis, structure, characterisation and biological activities discussed.

2013年12月12日 · We have developed a simple and effective way of preparing alkyl- and aryl-substituted ligand precursors in the form of diphosphine monosulfides, and demonstrated that in the presence of a metal these compounds ‘open up’ to give the desired bidentate ligand.

2021年1月1日 · The dppm ligand of this complex fits into the minor groove of the DNA and participate in hydrophobic interactions with the base pairs in the minor groove and the dfppy group placed away from the gap.

2022年9月23日 · Small bite-angle diphosphines such as the ubiquitous dppm [bis(diphenylphosphino)methane] have attracted much interest over the years as an excellent chelating or bridging ligand for mononuclear and polynuclear metal centres.

2016年7月7日 · Compared to the dppb ligand, the dppm ligand exhibits obvious rigidity, leading to ring formation, as in complexes 1 and 2. In view of the flexibility of the dppe ligand, it may show the features of a bridging ligand.

The bis(diphenylphosphino)methane (DPPM) functionalized amidinate ligand was obtained by a two-step synthesis route on a multigram scale (Scheme 1). First, DPPM was reacted with n-BuLi, leading to deprotonation of the methylene moiety. Subsequently, bis(2,6-diisopropylphenyl)carbodiimide was added to the reaction mixture to obtain the lithium ...

Ligand backbone alkylation of the complex [Cr(CO)4(dppm)] (dppm = bis(diphenylphosphino)methane) with alkyl iodides yields the C-substituted dppm ligand complexes [Cr(CO)4{Ph2PCH(R)PPh2}] (R = methyl, n-hexyl, benzyl).

2025年2月5日 · The stability of a methane diruthenium complex with either a dppm or dmpm (1,1-bis(dimethylphosphino)methane) ligand has also been computationally investigated, with the less sterically demanding dmpm forming a more stable methane complex than …
