Palladium(II) complexes of (t-butyl salicylidene) diphenyl disulfide diamine: synthesis, structure, spectral characterization and catalytic properties

Thio-Schiff bases derived from 2,2'-disulfanedianiline via nanocerium oxide: antimicrobial effect and antiproliferative effects in melanoma cells

“…Besides, in compounds 4a, 4b and 4c, characteristic peaks belonging to the υ (C-NO 2 ) group were observed at 1345 cm −1 , 1337 cm −1 and 1533 cm −1 , respectively. Moreover, the sharp, extended vibrations of the υ (C=N) (azomethine) group, which form the foundation of the Schiff bases, were observed in the range of 1620–1609 cm −1 [ 30 , 31 ]. Specific peaks of υ (C=C Ar ), υ (C-O Ar ), υ (C-S) [ 32 ] and υ (S-S) were observed in the ranges of 1487–1428, 1292–1249, 754–735 and 595–555 cm −1 [ 33 , 34 ], respectively.…”
