Abstract
The addition of secondary phosphine oxides to tetramesityldisilene and -digermene results in the mild, partial reduction of the P(V) centre of the organophosphorus oxide to P(III) to yield disilyl and digermyl phosphinite derivatives and illustrates the potential of ditetrelenes to serve as mild reducing agents under ambient conditions. An analogous reaction happens with <i>H</i>-phosphonates. Mechanistic experiments, including deuterium-labelling, kinetic isotope effect (KIE) and variable time normalization analysis (VTNA) experiments, reveal that the 1,3-PH addition likely proceeds through a stepwise reaction pathway with the organophosphorus oxide acting as the nucleophile towards the ditetrelene. Furthermore, a facile exchange between the R<sub>2</sub>PO- moiety on the digermylphosphinite with the R<sub>2</sub>PO moiety of phosphine oxides was discovered and likely proceeds through a direct substitution mechanism.

Abstract
The use of a bis(diphenyl)phosphine functionalized β-diketiminato ligand, [HC{(CH3 )C}2 {(ortho-[P(C6 H5 )2 ]2 C6 H4 )N}2 ]- (PNac), as a support for germanium(II) and tin(II) chloride and phosphaketene compounds, is described. The conformational flexibility and hemilability of this unique ligand provide a versatile coordination environment that can accommodate the electronic needs of the ligated elements. For example, chloride abstraction from [(PNac)ECl] (E=Ge, Sn) affords the cationic germyliumylidene and stannyliumylidene species [(PNac)E]+ in which the pendant phosphine arms associate more strongly with the Lewis acidic main group element centers, providing further electronic stabilization. In a similar fashion, chemical decarbonylation of the germanium phosphaketene [(PNac)Ge(PCO)] with tris(pentafluorophenyl)borane affords a "push-pull" stabilized phosphinidene in which one of the phosphine groups of the ligand backbone associates with the low valent phosphinidene center.

Abstract
The first examples of pyrene-fused Janus-type N-heterocyclic germylenes (NHGe) are reported. Remarkably, the pyrene linker and the germanium containing rings are extremely twisted, with "twist angles" up to 64°. Coordination of a Lewis base modifies the twisting of pyrene to an overall bent core (141° bend angle).

Abstract
N-heterocyclic ylide-like germylene effectively promotes the hydroboration of aldehydes and ketones under mild conditions with broad substrate tolerance, operational simplicity of procedure and excellent yields. A key intermediate in this catalytic system featuring a bicyclo[2,2,2]octane-like core has been successfully isolated and characterized, suggesting a new type of mechanism that involves the activation mode that mimics that of transition metal catalysts.

Abstract
The addition reaction of germylenoid H2GeFMgF with ethylene (C2H4) was first investigated in this work. All of the stationary points were optimized using the M062X method in conjunction with the 6-311[Formula: see text]G (d, p) basis set and the corresponding energies were calculated using the QCISD method with the 6-311[Formula: see text]G (d, p) basis set. The calculated results demonstrated that there are two different channels in the addition reaction of H2GeFMgF with C2H4, while only the channel I is feasible once the C2H4approaches H2GeFMgF in the proper conditions. The solvent effect upon the addition reaction was also investigated using PCM model. The results demonstrated that the tetrahydrofuran (THF) solvent could accelerate the addition reaction.

Abstract
Two newly discovered linear compounds tetraboronate and boroxine stabilized by digermylene are reported, which feature a B4O5 chain and a B3O3 ring, respectively. DFT calculations reveal that not only can digermylene stabilize the electron-deficient boron centers, but also increase the energies of the LUMOs of the boron moiety. Our results provide a hint for the development of boronate covalent organic frameworks.

Abstract
While β-diketiminate (BDI or ‘nacnac’) ligands have been widely adopted to stabilize a wide range of metal ions in multiple oxidation states and coordination numbers, in several occurrences these ligands do not behave as spectators and participate in reactivity.
