Ring-alkyl connecting group effect on mesogenic properties of p-carborane derivatives and their hydrocarbon analogues

Beilstein Journal of Organic Chemistry, 2009
The effect of the phenyl–alkyl connecting group on mesogenic properties of several series of isostructural compounds containing p-carborane (A and B), bicyclo[2.2.2]octane (C), and benzene (D) was investigated using thermal and optical methods.

Exploiting the Electronic Tuneability of Carboranes as Supports for Frustrated Lewis Pairs

Molecules, 2018
The first example of a carborane with a catecholborolyl substituent, [1-Bcat-2-Ph-closo-1,2-C2B10H10] (1), has been prepared and characterized and shown to act as the Lewis acid component of an intermolecular frustrated Lewis pair in catalyzing a Michael

Theoretical study of acidity of dicarbacloso-dodecaboranes(12) and their chloroderivatives

Тонкие химические технологии, 2008
Quantum-chemical calculation of o-, m-, p-carboranes(12) and C2H2B10Cl10 has been carried out by RHF, DFT(B3LYP) and MP2 methods (6-31G** and 6-311++G**). The analysis of electronic structure of these molecules has been performed.
