Abstract
The conceptual replacement of nitrogen with phosphorus in common organic functional groups unlocks new properties and reactivity. The phosphorus-containing analogues of triazenes are underexplored but offer great potential as flexible and small bite-angle ligands. This manuscript explores the synthesis and characterisation of a family of air-stable azophosphine-borane complexes, and their subsequent deprotection to the free azophosphines. These compounds are structurally characterised, both experimentally and computationally, and highlight the availability of the phosphorus lone pair for coordination. This is confirmed by demonstrating that neutral azophosphines can act as ligands in Ru complexes, and can coordinate as monodentate or bidentate ligands in a controlled manner, in contrast to their nitrogen analogues.

Abstract
The reaction of the stannyl phosphaketene (Nacnac)SnPCO 1 (Nacnac = CH{(CMe)(2,6-iPr2C6H3N)}2) with B(C6F5)3 produced the 1,4-addition product of (Nacnac)SnPCO(B(C6F5)3). However, the corresponding reactions in the presence of dimethyl maleate, diisopropyl fumarate or diethyl-but-2-ynedioate gave [2+2] addition yielding four-membered phosphacycles, ((Nacnac)Sn(MeO2C))CHPC(OB(C6F5)3)CH(CO2Me), [(C6F5)3B)PC(OSn)C(CO2Me)CH(CO2Me)]2, (Nacnac)Sn(iPrO2C)CC(OAl(C6F5)3)P[CH(CO2iPr)CH2(CO2iPr)]CH(CO2iPr), and (Nacnac)SnP (EtO2CCC(CO2Et))CO(B(C6F5)3), respectively. In contrast, the corresponding reaction of phenylacetylene gave the FLP-addition product (Nacnac)SnOC(P)C(Ph)CH(B(C6F5)3). Collectively, this reactivity demonstrates that the stannyl phosphaketene 1 can act as a synthon for P-analogues of β-lactam derivatives.

Abstract
![]()
Appetite for reactions
involving PH3 has grown in the
past few years. This in part is due to the ability to generate PH3 cleanly and safely via digestion of cheap metal phosphides
with acids, thus avoiding pressurized cylinders and specialized equipment.
In this perspective we highlight current trends in forming new P–C/P–OC
bonds with PH3 and discuss the challenges involved with
selectivity and product separation encumbering these reactions. We
highlight the reactivity of PH3 with main group reagents,
building on the early pioneering work with transition metal complexes
and PH3. Additionally, we highlight the recent renewal
of interest in alkali metal sources of H2P– which are proving to be useful synthons for chemistry across the
periodic table. Such MPH2 sources are being used to generate
the desired products in a more controlled fashion and are allowing
access to unexplored phosphorus-containing species.

Abstract
The germylene species (CH{(CMe)(2,6‐iPr2C6H3N)}2)GePCO 1 is shown to react with the Lewis acids (E(C6F5)3 E=B, Al). Nonetheless, 1 participates in FLP chemistry with electron deficient alkynes or olefins, acting as an intramolecular FLP. In contrast, in the presence of B(C6F5)3 and an electron rich alkyne, 1 behaves as Ge‐based nucleophile to effect intermolecular FLP addition to the alkyne. This reactivity demonstrates that the reaction pathway is controlled by the nature of the electrophile and nucleophile generated in solution, as revealed by extensive DFT calculations.

Abstract
Over the past decade, the reactivity of 2-phosphaethynolate (OCP-), a heavier analogue of the cyanate anion, has been the subject of momentous interest in the field of modern organometallic chemistry. It is used as a precursor to novel phosphorus-containing heterocycles and as a ligand in decarbonylative processes, serving as a synthetic equivalent of a phosphinidene derivative. This perspective aims to describe advances in the reactivities of phosphaethynolate and arsaethynolate anions (OCE-; E = P, As) with main-group element, transition metal, and f-block metal scaffolds. Further, the unique structures and bonding properties are discussed based on spectroscopic and theoretical studies.

Abstract
Primary acyl-phosphines are scarce in the literature. Here we show that the reaction of Ph3 GePCO with the ylide Ph3 PCH2 proceeds to give the species Ph3 PCHC(O)PH(GePh3 ) 1. Deprotonation of 1 with Na[N(SiMe3 )2 ] generates the salt [Na(THF)2 ][Ph3 PCHC(O)P(GePh3 )] 2 which provides subsequent access to the bis-germanylated acylphosphine, Ph3 PCHC(O)P(GePh3 )2 3. Alternatively, treatment of 1 with HCl in dioxane affords the primary acylphosphine Ph3 PCHC(O)PH2 4. Compound 4 is a rare example of an air stable primary acyl-phosphines and the first devoid of a stabilizing heteroatom adjacent to the carbonyl fragment.

Abstract
![]()
The
synthesis and thermal redox chemistry of the first antimony
(Sb)– and bismuth (Bi)–phosphaketene adducts are described.
When diphenylpnictogen chloride [Ph2PnCl (Pn = Sb or Bi)]
is reacted with sodium 2-phosphaethynolate [Na[OCP]·(dioxane)x], tetraphenyldipnictogen (Ph2Pn–PnPh2) compounds are produced, and an insoluble
precipitate forms from solution. In contrast, when the N-heterocyclic carbene adduct (NHC)–PnPh2Cl is combined
with [Na[OCP]·(dioxane)x], Sb–
and Bi–phosphaketene complexes are isolated. Thus, NHC serves
as an essential mediator for the reaction. Immediately after the formation
of an intermediary pnictogen–phosphaketene NHC adduct [NHC–PnPh2(PCO)], the NHC ligand transfers from the Pn center to the
phosphaketene carbon atom, forming NHC–C(O)P-PnPh2 [Pn = Sb (3) or Bi (4)]. In the solid
state, 3 and 4 are dimeric with short intermolecular
Pn–Pn interactions. When compounds 3 and 4 are heated in THF at 90 and 70 °C, respectively, the
pnictogen center PnIII is thermally reduced to PnII to form tetraphenyldipnictines (Ph2Pn–PnPh2) and an unusual bis-carbene-supported OCP
salt, [(NHC)2OCP][OCP] (5). The formation
of compound 5 and Ph2Pn–PnPh2 from 3 or 4 is unique in comparison to
the known thermal reactivity for group 14 carbene–phosphaketene
complexes, further highlighting the diverse reactivity of [OCP]− with main-group elements. All new compounds have been
fully characterized by single-crystal X-ray diffraction, multinuclear
NMR spectroscopy (1H, 13C, and 31P), infrared spectroscopy, and elemental analysis (1, 2, and 5). The electronic structure of 5 and the mechanism of formation were investigated using density
functional theory (DFT). An N-heterocyclic carbene (NHC) was used
to support the otherwise unstable Ph2Sb—P=C=O
and Ph2Bi—P=C=O moieties. Exploration
of the thermal chemistry of these NHC−phosphaketene adducts
reveals the formation of the salt [NHC2OCP][OCP]. This
present work demonstrates the thermal chemistry of the 2-phospaethynolate
anion with heavier pnictogens (Sb and Bi).

Reactions of Ph3GePCO with KP(t-Bu)2 and Ph3SiCl, or direct reaction with Ph3SiP(t-Bu)2 provides the (Z)- and (E)-isomers of the phosphaalkene (t-Bu2)PC(OSiPh3)P(GePh3) 2, respectively. These isomers interconvert thermally and photochemically, while 2 also undergoes silyl and phosphide exchange with silylphosphines, consistent with a mechanism involving the reversible silylphosphination of Ph3GePCO.

Abstract
The phosphaketene Ph3 GePCO is shown to react with the phosphide KP(tBu)2 to generate the anion [Ph3 GePC(O)P(tBu)2 ]- 1. This species reacts with CH3 I or ClGePh3 to give the dissymmetric diphospha-ureas (tBu)2 PC(O)P(GePh3 )(CH3 ) 2 and (Ph3 Ge)2 PC(O)P(tBu)2 3 respectively. Sequential treatment of 2 with a base and CH3 I affords a route to (tBu)2 PC(O)P(CH3 )2 5. These species are products of the first modular diphospha-urea synthesis. The subsequent thermal and photochemical reactivity of these species was also probed and described.

Abstract
We highlight recent advances in organopnictogen chemistry contrasting the properties of lighter and heavier pnictogens. Exploring new bonding situations, discovering unprecedented reactivities and producing fascinating opto-electronic materials are some of the most prominent directions of current organopnicogen research. Expanding the chemical toolbox towards the heavier group 15 elements will continue to create new opportunities to tailor molecular properties for small molecule activation/reactivity and materials applications alike. This frontier article illustrates the elemental substitution approach in selected literature examples.

Abstract
Acyl(chloro)phosphines RC(O)P(Cl)(t-Bu) have been prepared by formal insertion of tert-butyl phosphinidene (t-Bu–P) from t-BuPA (A = C14H10 or anthracene) into the C–Cl bond of acyl chlorides.
Acyl(chloro)phosphines RC(O)P(Cl)(t-Bu) have been prepared by formal insertion of tert-butyl phosphinidene (t-Bu–P) from t-BuPA (A = C14H10 or anthracene) into the C–Cl bond of acyl chlorides. We show that the under-explored acyl(chloro)phosphine functional group provides an efficient method to prepare bis(acyl)phosphines, which are important precursors to compounds used industrially as radical polymerization initiators. Experimental and computational investigations into the mechanism of formation of acyl(chloro)phosphines by our synthetic method reveal a pathway in which chloride attacks a phosphonium intermediate and leads to the reductive loss of anthracene from the phosphorus center in a P(v) to P(iii) process. The synthetic applicability of the acyl(chloro)phosphine functional group has been demonstrated by reduction to an acylphosphide anion, which can in turn be treated with an acyl chloride to furnish dissymmetric bis(acyl)phosphines.
