Boryl-substituted low-valent heavy group 14 compounds

Abstract

This review focuses on the low-valent heavy group 14 compounds stabilized by N-heterocyclic boryl ligands and their applications in the activation of small molecules and inert chemical bonds.

Recent advances in the chemistry of isolable carbene analogues with group 13–15 elements

“…Simultaneously, Inoue reported the silicon-carbonyl complexes 65 , underscoring the potential of disilylsilylene in CO coordination. 239 Moreover, in 2022, Cui introduced the disilicon dicarbonyl complex 66 , which enables the protonation of CO. 240 These discoveries show that the strong σ-donating boryl, 241 silyl and gallyl substituents play a vital role in the reactivity of the silylenes. In compound 64 , the C–Si bond length is reported to be 1.865 Å, which is indicative of a Si–C single bond.…”

Boryls, their compounds and reactivity: a structure and bonding perspective

“…One such area of current intense research is the field of boryls and their compounds, which have gained significant attention due to their unique reactivity. 1–5 The study of boryl compounds is expected to pave the way for the development of important applications in catalysis, materials science, and pharmaceuticals. 6–12…”

Carbene-Stabilized Phosphagermylenylidene: A Heavier Analog of Isonitrile

“…The N-heterocyclic boryl (NHB) groups, known for their electropositive nature, have been recently employed by the teams led by Jones, Aldridge, Yamashita, Cui, and our own group to stabilize low-coordinated main-group multiple bond species . This approach leverages the robust σ-donating and π-accepting ability and significant steric bulk of NHB to promote stabilization.…”
