Acyclic, Ring, and Cage As,C Compounds from Trimethylsilyl Ylides and AsCl<sub>3</sub>

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
