The reaction of 1,1,4,4‐tetrakis[bis(trimethylsilyl)methyl]‐1,4‐diisopropyl‐2‐tetrasilyne 1 with 1,3‐bis(cyanodimethylsilyl)propane 4 produced the 1:1 adduct, 1,4‐diaza‐2,3‐disilabenzene analog 5 as deep red crystals, which was characterized by spectroscopic data and X‐ray crystallography. Theoretical calculations on the reaction between the disilyne and silylcyanide show that the reaction proceeds via σ ‐coordination of silylcyanide, in which two molecules of silylcyanide coordinate with the sp‐silicon atoms of disilyne, enabling CC bond formation.
