The reaction between β-pinene and BF3·THF in the presence of the catalytic system Cp2TiCl2/Mg was carried out for the first time to obtain a 1-fluoro-substituted boraspirane, undescribed previously. The reaction proceeds stereoselectively, but is c

The present article details a novel approach for introducing strained 2,3-dimethylenebicyclo[2,2,0]hexane structures into the C60 fullerene molecule, based on the reaction of C60 with substituted propargylamines, promoted by the Ti(Oi-Pr)4 and EtMgBr

In this work, we propose a theoretical approach to distinguish fullerene C60 bis-cycloadducts with identical addends giving the same number of 13C NMR signals of sp2 fullerene carbon atoms. Trans-1 C60 bis-cycloadducts, including those that bear diff

The relationships between experimental and theoretical 13C NMR chemical shifts of a pristine fullerene C60, monoadducts from [2 + n] cycloaddition (n = 1–3), and one [2 + 1] bis-adduct are systematically analyzed for the first time by using diverse
