Synthesis and characterization of tris[butyl-(1-methyl-3phenyl-propyl)-dithiocarbamato]cobalt(III) seskvitoluen

Abstract

Anew bidentate ligand butyl-(1-methyl-3-phenyl-propyl)-dithiocarbamate (bm?pdtc) was prepared, as the sodium salt. In the reaction of hexaaminecobalt(III) chloride with Nabm?pdtc, the corresponding tris[butyl-(1-methyl-3-phenyl-propyl)-dithiocarbamato]cobalt(III) [Co(bm?pdtc)3]?complex was prepared. The complex was characterized by elemental analysis, infrared, electronic absorption, 1H and 13C-NMR spectroscopy.

Performance of Zinc-Difattyalkyldithyocarbamate as Anti-Friction/Anti-Wear Lubricant Additives

“…As antifriction/anti-wear additive, additive 2 does have a dominant performance, but does not show the antioxidant activity even lower the antioxidants, the same thing applies to additive 3. Antioxidant activity of additive 3 and additive 2 is lower than the form of RBDPO [19]. This fact reinforces the empirical evidence in the market that there is no additive which is multifunctional commercialized, while Zn-bis(lauryl palmityl)dithyocarbamate shows promise as an additive that has the performance as a powerful antioxidant and also can serve as anti-friction/anti-wear.…”

“…Dithyocarbamate organometallic compounds can also function as an antioxidant additive in lubrication systems [9,[19][20].…”

Synthesis of Zinc-Difattyalkyldithiocarbamates and Their Antioxidant Activities

“…Synthesis of Zn-difattyalkyldithiocarbamates were conducted according to the modified method of [3,[10][11], using closed reflux system. One mmol of secondary fatty amine dissolved in 30 mL diethyl ether then added with 0.2 mL CS 2 and 1 mmol NaOH.…”

Synthesis And Physico-Chemical Investigations On Some Bis(Carbodithioato)Nitrosyl Complexes Of Cobalt(I)

“…This range of 13 C signal for >NCS 2 group for its binding to the metal ion has also been reported by Rehman et al 21 13 C NMR signals due to 2,6-methylene (-CH 2 ) carbon atoms at δ 40.37-40.53 ppm, 3,5-methylene (-CH 2 ) carbon atoms at δ 40.04-40.21 ppm and CH 3 carbon at δ 39.71-39.87 ppm have also been observed to lie in the range for the respective carbon atoms of the heterocyclic ring. 16,22 (Table-3). 8 .…”
