Reference of 84127-04-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 84127-04-8, Name is Bis(4-methoxyphenyl)phosphine. In a document type is Article, introducing its new discovery.
A series of functionalized diphosphine bisgold(i) complexes have been prepared from the corresponding diphosphine ligands Ar4P2 (Ar = MeC6H4, MeOC6H4, Me2NC6H4) and characterized by NMR spectroscopy and APCI mass spectrometry. Single-crystal X-ray diffraction analyses were performed to study the presence and importance of unsupported aurophilic interactions for the structure formation of these compounds. In general, the complexes featured monomeric structures with an antiperiplanar arrangement of the two AuCl units. The crystal packing greatly depended on the position of the substitution pattern (ortho vs. para). While for the ortho-substituted systems (OMe and NMe2) no ordered 3-dimensional networks were observed, the para-functionalized compounds formed regular layer structures. Here, aurophilic Au?Au interactions only played a minor role compared to intermolecular pi?pi interactions and hydrogen bonds.
