Pyrrolidine dithiocarbamates of Pd(II)

Abstract

The dithioester (CH 2 ) 4 NCS 2 CH 3 (PyDTM, 1-pyrrolidinecarbodithioate methyl ester) has been prepared by reaction of the parent ammonium salt NH 4 PyDT ðPyDT ¼ ðCH 2 Þ 4 NCS

Synthesis, Characterization and Biological Evaluation of New Dithiocarbamate Ligand and Its Complexes with some Metal Ions

“…"The spectrum of NaL shows no band (disappeared) around 3222 cm -1 was assigned to υ(NH) stretching vibration, compared with that observed in the starting material [16]". "The IR spectrum reveals new band at 1446 cm -1 can be attributed to υ(C-N) stretching of (N-CS 2 ) moiety [17]". "Also the IR spectrum reveals two new bands at 1055 cm -1 and 942 cm -1 attributed to υ asy (CS 2 ) and υ sy (CS 2 ), respectively [18]".…”

Copper(II) complexes of pyrrolidine dithiocarbamate

“…For dithiocarbamate compounds, three main regions of IR are of interest. First, the 1580-1450 cm )1 region, which is primarily associated with the stretching vibration of C-N group of N-CSS ) moiety; second the 1060-940 cm )1 region, which is associated with m(-CSS) vibrations; third, the 420-250 cm [3].…”

“…There is an endothermic transition at 292°C corresponding to the melting point of the complex and an exothermic transition at 338°C due to removal of two PDTC ligands. The weight increase in the 360-600°C temperature interval is caused by nonstoichiometric oxygen uptake on the sample surface to form CuO, which releases oxygen at 710°C [3]. In Na[Cu(PDTC)I 2 ] decomposition starts at 170°C, resulting in the loss of PDTC ligand initially (weight loss of 31.9% against a calcd value of 30.0%) in the temperature interval of 170-287°C.…”

“…Metal complexes of dithiocarbamates have been widely studied in the recent years [1][2][3][4][5] because of their wide range of applications in agriculture as pesticides, in medicines, in industry as vulcanization accelerators, and in analytical and organic chemistry [6][7][8][9][10]. Their antimicrobial activity has been reported [2,5,11] and they have been used to fight metal poisoning [12].…”

Potent inhibitory effects of benzyl and p-xylidine-bis dithiocarbamate sodium salts on activities of mushroom tyrosinase

“…They are an integral part of industrialized agriculture and medicine, and are used against a broad spectrum of fungi and plant diseases caused by fungi 45 . Dithiocarbamates are used in health care for the management of alcoholism, and have been applied to prevent arthrosclerosis, and for antimicrobial and anti-inflammatory activity and metal transport in membranes 46 . It has been reported that dithiocarbamates can react with HS-containing enzymes and coenzymes of fungal cells, thus blocking their catalytic activity.…”
