Synthesis of C3-symmetric tris (1,1′-formylferrocenyl) stibine and bismuthine: Rare examples of tris 1,1′-asymmetrically ferrocenyl substituted group V compounds

Beyond phosphorus: synthesis, reactivity, coordination behaviour and catalytic properties of 1,1′-bis(diphenylstibino)ferrocene

“…In fact, compounds featuring C(ferrocenyl)–Sb bonds remain limited to a handful of examples (Scheme 2), considered mainly for possible donor–acceptor interactions between a pendant donor substituent and the stibine moiety. 10,11 The coordination behaviour and reactivity of these compounds remain virtually unexplored. 10 c…”

Synthesis, Structure, Reactivity, and Intramolecular Donor–Acceptor Interactions in a Phosphinoferrocene Stibine and Its Corresponding Phosphine Chalcogenides and Stiboranes

“…Until recently, ferrocene stibines were limited mainly to compounds E and F comprising a 1,2-disubstituted ferrocene backbone, which have been studied with a focus on the possible D → Sb interactions (D = adjacent donor moiety; for examples, see Scheme 1 ). 15 Earlier this year, we reported the synthesis of ferrocene distibine G ( Scheme 1 ), 16 a congener of the iconic ferrocene ligand 1,1′-bis(diphenylphosphino)ferrocene (dppf). 17 The facile conversion of this compound into isolable stiboranes and the differences in the reaction behavior of G and dppf led us to focus now on the mixed-donor analogue 1 , which represents the missing link between the two symmetrical ligands ( Scheme 1 ).…”

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

“…2 In the chemistry of ferrocene ligands, 3 compounds bearing stibine substituents were long limited to (diphenylstibino)ferrocene derivatives bearing donor groups at position 2 of the ferrocene scaffold, which were studied for possible Sb-donor interactions. 4,5…”
