Pnictogen bonding at the service of gold catalysis: the case of a phosphinostiborane gold complex

Abstract

The search for alternative gold catalyst activators has led us to consider the design of platforms in which a phosphine gold chloride moiety could be activated via formation of a...

Synthesis, reactivity and coordination behaviour of a ferrocene phosphinostibine and intramolecular interactions in its P(v) and Sb(v) derivatives

“…To further enhance the Lewis acidity of the antimony atom and thus elicit possible dative P/PE → Sb interactions, additional Sb( v ) derivatives were prepared via oxidation of compounds with free stibine groups with o -chloranil (3,4,5,6-tetrachloro-1,2-benzoquinone). Even in this case, direct oxidation of free phosphine 3 was rather difficult due to the poor selectivity 25 (Scheme 4). The reaction of 3 with 1 equiv.…”

The Potential of Self‐Activating Au(I) Complexes in Gold Catalysis

“…In a more recent development in 2024, Gabbaï's group have further contributed to the field of gold-stiborane complexes. [47] In this specific case, the catalyst self-activating properties arise from the incorporation of a catecholatostiborane (Sb V ) unit positioned adjacent to the gold chloride moiety, as shown in complex 17. As observed previously, the synergy between these two functionalities establishes an intramolecular Sb(V)•••ClÀ Au interaction, the formation of which benefits from the distinctive pnictogen bond donor properties of the antimony compound.…”
