A combined experimental and theoretical study of bimetallic bis- and tris-homocubane analogues

Abstract

Various bimetallic bis- and tris-homocubane analogues of group 9 transition metals have been isolated and structurally characterized employing Li[BH2E3] (E = S or Se).

Stabilization of dichalcogenide ligands in the coordination sphere of a ruthenium system

“…In order to compare the structural properties of the bis/tris-homocubane analogues and find out the influence of chalcogen atoms on the stability of these species, we have listed the spectroscopic and structural parameters of some selected bis-and tris-homocubane analogues in Table 2. 17,20,21 Among the bis-homocubanes analogues, the 1,3-isomer of bis-homocubanes containing metal, chalcogen and boron atoms is generally known. However, compound 5 is a unique example of bis-homocubane analogue which was isolated as a 1,4-isomer.…”

Metal‐Free Catalytic Functionalization of Second −Csp2−H Bond of 1‐Methyl Pyrrole Using Bishomocubane‐Derived Aminoborane Frustrated Lewis Pairs: A Computational Study

“…The scaffold size of bishomocubane is smaller than the previously reported adamantane scaffold and can be functionalized at different carbon centers [29] . The bishomocubanes can be substituted with nitrogen (N) and boron (B) derived functional groups; hence can be functionalized with amine (−NR 2 ) and borane (−BH 2 ) groups to generate the FLPs [30–35] . We have examined the reaction with 1,4 derivative of bishomocubane molecule as FLP scaffold.…”

“…[29] The bishomocubanes can be substituted with nitrogen (N) and boron (B) derived functional groups; hence can be functionalized with amine (À NR 2 ) and borane (À BH 2 ) groups to generate the FLPs. [30][31][32][33][34][35] We have examined the reaction with 1,4 derivative of bishomocubane molecule as FLP scaffold. 1,4-bishomocubane molecule is reported to be more stable compared to other bishomocubane derivatives (i. e., 1,3-1,2-and 1,1-bishomocubanes) as two cyclobutane rings are on the opposite faces to each other (Scheme 1, structure 2).…”
