2,6-Bis({rac-1-[2-(diphenylphosphino)ferrocenyl]ethyl}aminocarbonyl)pyridine

Abstract

The title compound, [Fe2(C21H21N3O2)(C17H14P)2], a new potential penta­dentate ligand with (non‐crystallographic) C2 axial symmetry, shows intra­molecular π–π inter­actions and weak C—H⋯O hydrogen bonds in the crystal structure.

Crystal structure of bis{(S)-1-[2-(diphenylphosphanyl)ferrocenyl]-(R)-ethyl}ammonium bromide dichloromethane monosolvate

“…A search of the Cambridge Structural Database (Version 5.37; last update March 2016; Groom et al, 2016) for structures of molecules containing an analogous tridentate ferrocene PNP scaffold revealed no entries. However, three molecules where the secondary amine functionality is replaced by a longer linker were found: AZAHED (amine substituted for imidazolium; Gischig & Togni, 2005), ALEZMOS (2,6-pyridine dicarboxamide; Reddy et al, 2007) and PEDTEX (piperazine; Zhou & Zhang, 2005). Finally, in XARUD (You et al, 2000) the amine functionality is substituted by a cyclohexanediamine unit.…”

Copper-mediated intramolecular oxidative N-dealkylation of a bis(ferrocenyl)pyridyl ligand

“…In fact, some of them are copper-selective. We have recently prepared and reported the crystal structure of a bis(ferrocenyl)pyridyl amide (Scheme 1) [7]. In addition, we prepared the phenyl analogue of this ligand for comparative reactivity studies, as shown in Scheme 1.…”
