Bonding Nature of B2L2‑SiR2 (L = NHC, Silylene; R = H, Cl): Metallomimetic, Silylene, or Diboryne?
Low-valent main-group compounds represent a highly active frontier field, owing to their unique bonding characteristics and transition-metal-like reactivity in activating inert small molecules. As prototypical systems, diborynes and silylenes have attracted considerable attention, yet the fundamental nature of their bo...
