Summary: This article provides a detailed overview of the synthesis, reactivity, structural features, and catalytic activities of acyl phosphines and bis(acyl) phosphines reported in the last three decades. Although acyl phosphines have been known historically, their literature is not exhaustive due to the vulnerability of P-C(O) bonds toward nucleophilic substitution reactions. However, there has been a renewed interest in the synthesis of acyl phosphines and di(acyl) phosphines recently, with the examples of phosphines possessing two acyl groups found more frequently in the literature. Transition-metal complexes of acyl phosphines and di(acyl) phosphines have been moderately explored, but their catalytic applications are limited.

Summary: Several novel ionic phosphines (L1-L4) with good robustness against water and oxygen were synthesized and characterized. The XPS analysis showed that L1 derived from Xantphos could act as a P, O-hybrid ligand with P, O-chelation to Pd-center. As a result, L1 provided PdCl2(MeCN)2 with high catalytic activity, excellent selectivity, and good stability in the bis-hydroaminocarbonylation of alkynes, yielding N-aryl substituted succinimides with isolated yields of 57-90%. Control experiments and in situ high-pressured FT-IR analysis further confirmed that the studied reaction followed a tandem reaction mechanism involving Pd-H species (m 1942 cm-1) over the L1-Pd(MeCN)2Cl2 catalytic system.

Summary: We report a facile and highly modular access to an intriguing class of free Au-substituted phosphines (AuPhos). Au-substitution can boost the electron-releasing ability of AuPhos, leading to an electronically and sterically tunable, extremely electron-rich phosphorus center. Multi-nuclear transition metal complexes ligated by AuPhos are readily prepared, and preliminary catalytic results show the facilitation of C-N coupling reactions and decarbonylation reactions. This work provides insights for future development of electron-rich ligands.

Summary: The synthesis of a silyliumylidene cation complex 2 stabilized by a Ni-0-based donating ligand is described. Experimental and theoretical studies show that the highly electrophilic Si-II center is stabilized by a dative Ni -> Si sigma-interaction and pi-donations from the amino- and Ni-moieties. Due to similar energy levels of the frontier orbitals localized on the Si and Ni atoms, complex 2 exhibits competitive reactivity at both Si and Ni sites.

Summary: A comparison study of mono- and bisphosphine ligands in Ni-catalyzed Suzuki-Miyaura cross-coupling reactions revealed that monophosphines exhibit higher reactivity, particularly with electronically deactivated and sterically hindered substrates. Mechanistic experiments showed that monoligated (P1Ni) species accelerate the organometallic steps of the catalytic cycle, while bisligated (P2Ni) species prevent off-cycle reactions and catalyst poisoning by heterocyclic motifs. These findings provide guidelines for ligand selection against challenging substrates and future ligand design tailored to the mechanistic demands of Ni-catalyzed cross-coupling reactions.

Summary: The synthesis of B9-Phos ligands with two carboranyl moieties and bulky electron-donating substituents, previously deemed unattainable, is reported. The electrochemical properties of B9-Phos ligands were investigated, showing the ability of mesityl derivatives to form stabilized phosphoniumyl radical cations. The B9-Phos ligands possess a highly electron-releasing character surpassing that of alkyl phosphines and commonly used N-heterocyclic carbenes.
