“…45−49 Significantly, it has been demonstrated that the resonance structure for the phosphoniophospholide XII can best be described as shown in XIIb, which features a 6πaromatic phospholide moiety. 50 The same group also synthesized the stannaindene XIII, 51 and later its silicon analogue XIV was reported by Driess et al 52 These pioneering studies prompted us to develop a bis(NHO) derivative, IX, and investigate its coordination chemistry with main-group elements. Herein we report the synthesis of bis(NHO) derivatives and its utility as a precursor to develop isophosphindolylium and the reactivity of the latter as a two-electron donor ligand.…”

We have developed bis(N-heterocyclic olefin) derivatives 2 and demonstrated that 2 can be utilized as precursors for the synthesis of isophosphindolylium species 3. X-ray diffraction and density functional theory studies indicate the aromatic property of the PC five-membered ring in 3. Despite its cationic nature, the P center in 3b exhibits nucleophilic character and thus readily forms a bond with CuCl to afford a copper phosphenium complex 4, demonstrating the potential utility of 3 as a σ-donor ligand.

“…In addition to ylide‐substituted carbenes synthesized by the groups of Kawashima and Fürstner, [6] Driess et al. in 2011 succeeded in synthesizing ylide‐substituted silylenes Ia and Ib (Figure 1), [7] based on a cyclic scaffold earlier used by Schmidpeter and coworkers for the isolation of a stannylene [8] . Five years later, the group of Kato reported on the cyclic amino(ylide)silylene IIa , [9] which based on crystallographic, NMR and computational data featured a strong π‐donation from the ylide to the silicon center, consistent with structure II’ being the most accurate description of the the electronic structure.…”

The synthesis and structure analysis of a series of mono and diylide‐substituted tetrylenes of type YEX and Y2E (E=Ge, Sn, Pb; X=Cl or Br) using a thiophosphinoyl‐tethered metallated ylide (Y=Ph2P(S)−C−P(pip)Ph2 with pip=piperidyl) is reported, amongst the first ylide‐substituted plumbylenes. The tetrylenes feature distinct trends in the spectroscopic and structural properties of the ylide ligand with increasing atomic number of the tetrel element. For instance, an increasingly high‐field shifted signal for the thiophosphinoyl group is observed in the 31P{1H} NMR spectrum as a consequence of the increasing polarity of the element‐carbon bond, which likewise results in a shortening of the ylidic C−P bond in the solid‐state structure. The diylidyltetrylenes are unstable towards transylidation forming the mono(ylide)tetrylenes when treated with the tetrel dihalides according to the stability trend: Y2Pb
