“…Phospholides are one of the two fundamental aromatic rings of phosphorus–carbon heterocyclic chemistry . However, the number of synthetic routes to these species is very limited in spite of their key role in organophosphorus synthesis and coordination chemistry.…”

“…The breaking of P─P bonds in the T ‐Sc 20 C 48 P 12 ‐1 cluster is attributed to the difficulty of each phosphorus atom to achieve a sp 2 hybridization (planar) avoiding the interaction of its lone pair with neighboring carbon atoms. The pentagonal rings are related to phospholide anions (C 4 P ‐ ), and P atoms might easily participate in other chemical reactions (i.e., formation of phospholes) . T ‐Sc 20 C 48 P 12 ‐1 is stable in the 0 and ‐1 states, but its hydrogenated structure is only lacking on imaginary frequencies when a ‐1 charge state is sustained.…”

“…Aforementioned results inspired us to dope the volleyballene with trivalent heteroatoms such as P and N atoms . Nitrogen atom is known to form C─N bonds that are covalent and shorter than C─C bonds in diamond (1.53

In this study, the heteroatom doping of volleyballene with N and P atoms and the hydrogenation of their related structures is addressed, with an emphasis on the displayed bonding, adsorption energies, and vibrational properties. It is determined that the doping with 12 phosphorus atoms ([Sc20C48P12]‐1] produces a tetrahedral‐like (T point group) structure. Conversely, the presence of 12 nitrogen atoms results in a structure (C2H‐Sc20C48N12) maintaining the parent volleyballene framework. The N‐doping structure displays a calculated hydrogen adsorption energy of ‐0.20 eV/H (Sc20C48N12H24), and it increases to ‐0.50 eV/H in the case of the structure doped with P atoms ([Sc20C48P12H36]‐1). The predicted four new structures are attested as true minima by their IR and Raman spectra. Finally, the assignment of their IR/Raman signals is carried out in order to facilitate their experimental detection.

“…Among the various heterometallocenes reported to date, phosphaferrocenes are by far the most investigated because of their structural and electronic features [1,2] and remain the objects of growing interest in the fields of coordination chemistry [3,4,5] and asymmetric catalysis [6,7]. Due to the sp 2 -hybridization of the phosphorus atom, phosphaferrocenes are commonly regarded as phosphorus ligands with weaker σdonor character than classical tertiary phosphines and stronger π-acceptor properties closer to phosphites P(OR)3 [8,9].…”

A novel representative of sodium 3,4,5-triaryl-1,2-diphosphacyclopentadienide containing Cl-substituent in the meta- position of the aryl groups was obtained with a high yield based on the reaction of (1,2,3-triarylcyclopropenyl)tributylphosphonium bromide and sodium polyphosphides. Further reaction of sodium 3,4,5-tri(3-chlorophenyl)-1,2-diphosphacyclopentadienide with [FeCp(η6-C6H5CH3)][PF6] complex gives a new 3,4,5-tris(3-chlorophenyl)-1,2-diphosphaferrocene. The electrochemical properties of 3,4,5-tris(3-chlorophenyl)-1,2-diphosphaferrocene were studied and compared with 3,4,5-tris(4-chlorophenyl)-1,2-diphosphaferrocene. It was found that the position of the chlorine atom in the aryl fragment has a influence on the reduction potential of 1,2-diphosphaferrocenes, while the oxidation potentials do not change..
