- Arylpentazoles revisited: Experimental and theoretical studies of 4-hydroxyphenylpentazole and 4-oxophenylpentazole anion
-
Kinetic measurements for the degradation of 4-hydroxyphenylpentazole (2a) and its salt 2b-NBu4 in CD3OD and in CD2Cl2 provided a set of activation parameters. The resulting free energies of activation in methano

- Experimental detection of the pentaazacyclopentadienide (pentazolate) anion, cyclo-N5-
-
The long-sought pentazolate anion, cyclo-N5-, the isoelectronic polynitrogen counterpart of the cyclopentadienide anion, has been experimentally detected for the first time. Using electrospray ionization mass spectrometry and carefully selected collision voltages, the aryl substituent in the para-pentazolylphenolate anion can be removed selectively without breaking the nitrogen-nitrogen bonds of the pentazolate anion (see scheme), thus delineating a synthetic method for the bulk synthesis of N5-.

- The photochemistry of an aryl pentazole in liquid solutions: The anionic 4-oxidophenylpentazole (OPP)
-
This paper reports a study on the photolysis of an aryl pentazole in solution. 4-Oxidophenylpentazole (OPP) was irradiated in water and in acetonitrile at its first absorption band (320 and 370 nm, respectively) and at 193 nm. 4-Oxidophenylazide (OPA) was

- Synthesis and characterization of eight arylpentazoles
-
p-Nitrophenyl-, p-methoxyphenyl-, p-hydroxyphenyl-, p-t-butylphenyl-, p-HOSO2-phenyl-, 15N-p-N,N-dimethylaminophenyl-, 15N2-p-N,N-dimethylaminophenyl-, and dicyanoimidazopentazole were obtained via different synthetic routes. Cesium, barium, potassium, and sodium salts of the arylpentazoles bearing acidic hydrogens were prepared. NMR spectra (1H, 13C) are reported for the arylpentazoles, their corresponding arylazides, and their salts.
