A silyne seeker : The synthesis of the first isolable silyne, which is stabilized by a phosphine ligand, has been achieved (see picture). An X‐ray diffraction study reveals a very short silicon–carbon bond, as predicted computationally for SiC bonds. This species has a certain degree of carbenic character, and this result shows that the phosphonium sila‐ylide fragment acts as a strong π‐donating and π‐accepting substituent.
