Synthesis, catalytic and antibacterial activity of 2-aminophenyldisulphide

Abstract

Metal complexes 1a-1c have been synthesized using 2-aminophenyldisulphide, 1, while 2d and 2e were synthesized from 2-hydroxybenzaldehyde phenyldisulphide diimine, 2. All complexes were characterized by elemental analysis, spectroscopic data and magnetic moments. At room temperature complexes 1a, 2a-2c and 3b catalyse the oxidation of primary alcohols and cyclohexene using NMO or H 2 O 2 as co oxidant. The compounds 1-6 and some metal complexes were evaluated for their antibacterial activities against gram-positive and gramnegative bacteria.

“…For the preparation of multidentate chelating agents using 2,2 0 -dithiobis(benzenamine) as starting material, see: Bhowon et al (2001Bhowon et al ( , 2005Bhowon et al ( , 2007; Nag et al (2001); Okachi et al (1985); Uma & Palanaindavar (1993); Jhaumeer & Bhowon (2003).…”

“…We have been interested in the synthesis and properties of potential ligands which can be prepared from 2,2′-dithiobis-(benzenamine). From this starting material, one can envisage the preparation of multidentate chelating agents having nitrogen, oxygen and sulfur donor atoms of relevance for the study of various mode of coordination (Okachi et al, 1985;Bhowon et al, 2001;Jhaumeer Laulloo & Bhowon, 2003;Bhowon et al, 2007;Nag et al, 2001;Uma & Palanaindavar, 1993;Bhowon et al, 2005). In the present work 2,2′-dithiobis(benzenamine) N,N′-bis(furan-2-carboxamide) was synthesized (Scheme 1) with a view to examining the stereochemistry of the compound.…”

Synthesis, antibacterial activities and phospholipid membrane interactions of novel dialkyl 2,2’-disulfanediyldibenzoates

“…Moreover, many biologically active compounds including proteins, prodrugs and vulcanizing agents have disulfide linkages [2]. A number of diaryldisulfides compounds containing different functional groups have been reported to exhibit various properties such as anti-leishmanial [3], anti-oxidant [4], anti-HIV [5,6] and anti-bacterial properties [7][8][9][10].…”
