Electron impact partial ionization cross sections: R-carvone, 2-butanol, imidazole, and 2-nitroimidazole [PDF]
, 2023 We theoretically calculate the electron impact partial and total ionization cross sections of R-carvone $(\mathrm{C_{10}H_{14}O})$, 2-butanol $(\mathrm{C_{4}H_{10}O})$, imidazole $(\mathrm{C_3H_4N_2})$ and 2-nitroimidazole $(\mathrm{C_3H_3N_3O_2})$. We have used the Binary Encounter Bethe (BEB) model to obtain the total electron impact ionization cross

Syntheses of polyalkylated imidazoles
Synthetic Communications, 2017 We have developed improved general simple methods for large-scale preparation of polyalkylated imidazoles by improved multicomponent synthesis from commercially available starting materials. A large range of NH- and N-alkyl-polyalkylimidazoles (40 in total, including novel compounds) has been synthesized.
