Abstract

Laser desorption ionization (LDI) time-of-flight (TOF) mass spectroscopy of solid p- dimethylaminophenylpentazole (1) gives strong peaks of m/z− 42 and− 70. The− 70 peak was identified by 15N labeling of 1 to be the pentazolate anion (cyclo-N5−). The pentazolate anion is formed by an electron attachment to 1 forming the corresponding radical anion followed by a decomposition into 4-N (CH3) 2-C6H4 and (cyclo-N5−). The LDI TOF ...
