The cyclization reactions of naphthalene-fused azo-ene-yne compounds are explored both computationally and experimentally. Calculations reveal that naphtho-fusion to an azo-ene-yne scaffold does not significantly alter the transition state energies c

Dications of 9-(3-phenyl-1H-inden-1-ylidene)-5H-dibenzo[a,d]cycloheptene, 5(2+), were prepared by oxidation with SbF(5) in SO(2)ClF, and their magnetic behavior was compared to dications of 9-(3-phenyl-1H-inden-1-ylidene)-9H-fluorene, 2(2+). The good

An isomeric pair of 15-membered dehydrobenzopyridannulenes functionalized with -NBu(2) groups as pi-electron donors was prepared and their steady-state spectroscopic parameters investigated. The property differences arising from placement of the pyri

A new method for the generation of dicationic species via ionization of diols is described. The method makes use of milder reagents at room temperatures, an advantage over use of Magic Acid at −78 °C. A series of mono- and dications were synthesiz

Urea and sulfonamide derivatives of 1 exhibit ON–OFF and OFF–ON switchable fluorescent and colorimetric responses upon protonation. The magnitude of the fluorescence event is dictated by the anion, resulting in a rare, fully organic “turn-on”

formula chem. The design of new reactions that yield benzo-fused five- or six-membered rings arising from conjugated ene-ene-yne precursors was examined computationally. Inclusion of heteroatoms (particularly N) in the bond making position was shown
