Publikováno v: Journal of Inclusion Phenomena and Macrocyclic Chemistry. 99:227-234
Direct short-wave photolysis of chlorpyrifos-methyl (1) and chlorpyrifos-methyl oxon (2) was studied in the presence of native cyclodextrins (α–, β– and γ–CD) and randomly methylated β–CD (RAMEB). We used for irradiation low pressure Hg l

Publikováno v: Organic & Biomolecular Chemistry. 19:208-215
Experimental and computational studies have been performed in order to investigate an unusual carbon-carbon bond cleavage that occurs in the preparation of certain benzimidazole N-oxides from anilines. The key factor determining the outcome of the re

Preparation of benzimidazole N-oxides by a two-step continuous flow process
Autor: Elba I. Buján, Fabrizio Politano, Nicholas E. Leadbeater
A continuous flow process for the synthesis of nitrobenzimidazole N-oxides from 2,6-dinitrochlorobenzene and amines or amino acids is reported. The process, performed in a two-step sequence, is faster than previously reported batch processes and avoi

Stabilization of the pesticide Fenitrothion towardOandNnucleophiles in the presence of cyclodextrins
Autor: Rita H. de Rossi, Elba I. Buján, Natalia M. Rougier, Raquel V. Vico
Publikováno v: Journal of Physical Organic Chemistry. 27:935-943
The reaction of Fenitrothion with O and N nucleophiles (H2O2, NH2OH, n-butylamine and piperidine) was studied at 25 °C in water containing 2% 1,4-dioxane in the presence of native cyclodextrins (α-, β-, and γ-CD). For all the nucleophiles, the pr
