The reactions of 2--(Chloroseleno)benzoyl Chloride with Pyridine and Related Azines

Osajda M., Młochowski J.

Polish Journal of Chemistry

2002

Vol. 76 / nr 7

953-958

The reaction of 2-(chloroseleno)benzoyl chloride with pyridine and pyridine-like heterocycles such as pyrimidine, pyrazine, quinoline, phthalazine, phenazine and 1,10-phenanthroline was studied. In the most cases stable 2-(hydroxyseleno)benzoylazinium chlorides were produced depending on the number of the pyridinium-like nitrogen atoms and their situation in the ring system.

Bisbenzisoselenazol-3(2H)-ones, a New Group of Ebselen Analogues

Osajda M., Kloc K., Młochowski J., Piasecki E., Rybka K.

Polish Journal of Chemistry

2001

Vol. 75, nr 6

823-830

The title compounds with benzisoselenazolone moieties connected by spacers such as phenylene, bisphenylene, alkylene, oxaalkylene, azaalkylene and dithiaalkylene groups have been obtained in the reaction of 2-(chloroseleno)benzoyl chloride with compounds having two primary amine groups, while the secondary amines gave products of their selenenylation and/or acylation. Bisbenzisoselenazol-3(2H)-ones were found, in the antiviral assay in vitro, to be inhibitors of cytopathic activity of RNA and DNA viruses: EMCV, HSV-1 and VSV.
