Half a century of scrambling in organic ions: Complete, incomplete, progressive and composite atom interchange
Positional exchange of atoms within the given frameworks of gaseous ions and positional exchange of the framework atoms themselves-generally addressed as atom scrambling-belong to the best-known but,Expand
The Gas-Phase Basicity and Proton Affinity of 1,3,5-Cycloheptatriene—Energetics, Structure and Interconversion of Dihydrotropylium Ions
The hitherto unknown gas-phase basicity and proton affinity of 1,3,5-cycloheptatriene (CHT) have been determined by Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry. SeveralExpand
Mass spectrometry of alkylbenzenes and related compounds. Part I. Gas‐phase ion chemistry of alkylbenzene radical cations
From the vantage point of an organic chemist, many previously obscure fragmentation and isomerization processes of gaseous organic ions have become chemically reasonable reaction pathways. The termExpand
2,3,6,7,10,11‐Hexamethoxytribenzotriquinacene: Synthesis, Solid‐State Structure, and Functionalization of a Rigid Analogue of Cyclotriveratrylene
The syntheses of several tribenzotriquinacenes bearing six methoxy groups at the outer peripheral positions of the aromatic rings are reported. The centro-methyl derivative is accessible inExpand
Multiply bridgehead- and periphery-substituted tribenzotriquinacenes—highly versatile rigid molecular building blocks with C3v or C3 symmetry
The chemical versatility of tribenzotriquinacenes as building blocks bearing rigid carbon frameworks with convex/concave molecular surfaces is presented. As revealed by X-ray single crystal structureExpand
Mass spectrometry of alkylbenzenes and related compounds. Part II. Gas phase ion chemistry of protonated alkylbenzenes (alkylbenzenium ions)
Mass spectrometry and ion chemistry of alkylbenzenes, today, is much more than the gas-phase reactions of their radical cations and their prominent fragment ions, such as C7H7+ and C7Hs+'. Indeed,Expand
Merging tribenzotriquinacene with hexa-peri-hexabenzocoronene: a cycloheptatriene unit generated by Scholl reaction.
The single-wing extension of the bowl-shaped tribenzotriquinacene (TBTQ) framework with polycondensed aromatic hydrocarbon units has been reported. In the course of a Scholl reaction, one of theExpand
Functionalized aromatics aligned with the three Cartesian axes: Extension of centropolyindane chemistry
The unique geometrical features and structural potential of the centropolyindanes, a complete family of novel, 3D polycyclic aromatic hydrocarbons, are discussed with respect to the inherentExpand
Three-Fold Scholl-Type Cycloheptatriene Ring Formation around a Tribenzotriquinacene Core: Toward Warped Graphenes.
The bridging of each of the three T BTQ bays by 1,2-phenylene units in compound 6 gives rise to an unusual wizard hat shaped structure, which represents a promising key intermediate for the construction of nonplanar nanographene molecules bearing a TBTQ core. Expand
