We provide important novel insights into skeletal transformations of fullerene by reporting new cases cage shrinkage in the most abundant C60 via a C2 loss. High‐temperature (400–500 oC) chlorination IPR with SbCl5 or SbCl5/SbCl3 mixtures predominantly gives non‐IPR C60Cln compounds Stone‐Wales rearrangements, but present study further reveals non‐classical C58Cln chlorofullerenes as by‐products. The C58(NC1)Cl20 and C58(NC1)Cl24 chlorides have been isolated air‐free HPLC structurally...

Abstract High‐temperature trifluoromethylation of fullerene C 78 followed by HPLC separation (CF 3 ) n derivatives resulted in the isolation and X‐ray structural characterization 15 compounds, that is, two (1)(CF 10 , three 12 four 14 five 16 isomers as well one isomer 18 . The addition patterns molecules are discussed terms pathways relative formation energies.

Abstract We survey the structure and electronic properties of family higher trifluoromethylated C 70 (CF 3 ) n molecules with n= 14, 16, 18, 20. Twenty‐two available compounds, which thirteen are newly obtained characterized, demonstrate broad diversity π‐system topologies, enabled us to study interplay between CF addition pattern properties. UV/Vis spectroscopic cyclic voltammetric studies importance exact rather than plain number addends. Of particular interest is skew pentagonal pyramid...

We report a comprehensive study of novel isomer C70(CF3)12, p9mp-C70(CF3)12, whose electrochemical behavior differs from most the other trifluoromethylated fullerenes. The addition pattern p9mp-C70(CF3)12 is established by means 19F–19F COSY NMR spectroscopy and DFT calculations. Like p7mp-C70(CF3)10, new undergoes dimerization to [C70(CF3)12]22– upon single-electron reduction. observations are supported calculations energy temperature dependence CW X-band EPR data. Experimentally determined...

The combustion energy and standard molar enthalpy of formation crystalline 6-phenyl-1,5-diazabicyclo[3.1.0]hexane (PDABH) were determined using an isoperibolic calorimeter with a static bomb. PDABH is the first diaziridine for which experimental value was obtained. This validated by theoretical values gas phase sublimation. calculated DLPNO-CCSD(T1)/CBS method in conjunction isodesmic-type reactions. chosen comparison to another high quality evaluative (G4), has been shown provide unreliable...

Abstract Here we report a facile one‐pot regioselective synthesis of the family chiral 1,7‐C 60 (CF 2 )(CF 3 )R compounds via CF carbene addition to in situ generated C − anion. The simplest representative family, )Me, is unequivocally characterized and shown feature 0.1 eV lower LUMO level than , that makes it prospective electron accepting electron‐transport material.
