“…[1] It could be the main reason for the less explored chemistry of acyl phosphines when compared with that of other tertiary phosphine ligands. [2][3][4][5][6][7][8][9] Nevertheless, they are recently used as phosphine sources in catalytic C-P bond forming reactions. [10][11][12][13][14] It is observed that the P-C(O) bond lengths in acyl phosphines and di (acyl) phosphines are slightly longer than those of P-C (sp 2 ).…”

Acyl phosphines (R2P–C(O)R) are the tertiary phosphorus compounds having a P–C(O) linkages. Though they are known historically, their literature is not exhaustive mainly due to the vulnerability of P–C(O) bonds toward nucleophilic substitution reactions. However, there is a renewed interest in the synthesis of acyl phosphines and di (acyl) phosphines, recently. Among the methods available for the synthesis, most involve nucleophilic substitutions at carbonyl carbon by phosphorus nucleophile as a customary step. The examples of phosphines possessing two acyl groups (R(O)C–RP–C(O)R) are found more frequently in the literature of late, and most of them are cyclic in nature. The transition‐metal complexes of acyl phosphines and di (acyl) phosphines are moderately explored in literature. However, their catalytic applications are meager. In the current review, the details of syntheses, reactivity, structural features, and catalytic activities of acyl phosphines and bis (acyl) phosphines reported in the last three decades are discussed.

“…1,2,4 The dppf is a biphosphine ligand and can adopts numerous coordination modes in complexes of a range of transition metals. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] These dppf complexes have been utilized in several area such as catalysis, materials science, electrochemistry, and biology. 1,2,7,9,10,[19][20][21] On the other hand, the chemistry of cyclometalated complexes is of great interest because of their use in a wide range of applications.…”

The preparation and characterization of new heteronuclear-platinum(ii) complexes containing a 1,1'-bis(diphenylphosphino)ferrocene (dppf) ligand are described. The reaction of the known starting complex [PtMe(κN,C-bipyO-H)(SMe)], A, in which bipyO-H is a cyclometalated rollover 2,2'-bipyridine N-oxide, with the dppf ligand in a 2 : 1 ratio or an equimolar ratio led to the formation of the corresponding binuclear complex [PtMe(κN,C-bipyO-H)(μ-dppf)], 1, or the mononuclear complex [PtMe(κC-bipyO-H)(dppf)], 2, respectively. According to the reaction conditions, the dppf ligand in 1 and 2 behaves as either a bridging or chelating ligand. All complexes were characterized by NMR spectroscopy. The solid-state structure of 2 was determined by the single-crystal X-ray diffraction method and it was shown that the chelating dppf ligand in this complex was arranged in a "synclinal-staggered" conformation. Also, the occurrence of intermolecular C-HO interactions in the solid-state gave rise to an extended 1-D network. The electronic absorption spectra and the electrochemical behavior of these complexes are discussed. Density functional theory (DFT) was used for geometry optimization of the singlet states in solution and for electronic structure calculations. The analysis of the molecular orbital (MO) compositions in terms of occupied and unoccupied fragment orbitals in 2 was performed.
