Tetraethylthiuram disulphide

Experiments with animals demonstrate that DDTC could be used in conjunction with cisplatin chemotherapy325,326. For instance, pretreatment with DDTC protects against the nephrotoxicity of cisplatin therapy Wysor et al.327 have demonstrated the trypanocidal potential of cisplatin and tetraethylthiuram disulphide, the disulphide of DDTC... 

The Inifer technique enables us to fulfil some requirements of polymer architecture even in some radical processes. An amplified form may be applied, the Iniferter variant, where the radical initiator simultaneously acts as a transfer and terminating agent. Otsu et al. used sulphides and disulphides (tetraethylthiuram disulphide, PhSSPh, Ph2S, PhCH2SSCH2Ph) [96] and carbamates (benzyl-A,A-diethyldithiocarbamate, p-xylylene-A,7V-diethyl-dithiocarbamate) [97] in the photopolymerization of methyl methacrylate and styrene, and phenylazotriphenylmethane in the polymerization of methyl methacrylate [98]. Living radical polymerizations yield polymers with defined end groups or the required block copolymers.

Re(dtcEt2)4][Re(CO)3Cl(dtcEt2)1 (dtcEt2 = diethyldithiocarbamato) has been separated as one of the products following the reaction between Re(CO)5Cl and tetraethylthiuram disulphide the cation was separated as its BPh " salt. The oxidation and reduction characteristics of this cation have been determined in acetone solution with NaC104 as the supporting electrolyte, and an oxidation wave at 0.23 V vs. SCE) and two reduction waves at —0.65 and — 1.14 V (vs. SCE) were observed. ... 

Sulfiram (tetraethylthiuram monosulphide) is closely related to disulfiram (tetraethylthiuram disulphide) and can apparently undergo photochemical conversion to disulfiram when exposed to light. The longer it is stored, the higher the concentration. The reaction with alcohol appears therefore to be largely due to the presence of disulfiram, see Alcohol + Disulfiram ,... 

The polymer which is obtained when chloroprene is emulsion-polymerized in the absence of sulfur or a chain-transfer agent is a tough, insoluble non-plastic material. If sulfur is dissolved in the chloroprene prior to polymerization (at a level of 0.5-1.5 parts by mass per 100 parts by mass of monomer), the product is still a tough insoluble material which is unsuitable for use as an elastomer. However, by heating the latex obtained (still in an alkaline condition) with a thiophilic reagent, such as tetraethylthiuram disulphide (Vlll), the polymer becomes plasticized or peptized to a soft, plastic, soluble polychloroprene which is suitable for use as an elastomer. 

Free acid unstable and has not been isolated. Na and K salts sol HgO Ox. (I, ferncyanide, etc.) — tetraethylthiuram disulphide, Zn salt and organic amine salts (particularly the diethylamine salt) used as rubber vulcanisation accelerators. 

Oxidation of the intermediate phosphite triester can also be effected using elemental sulphur in CS2 (39), tetraethylthiuram disulphide in CH3CN (39), dibenzoyl tetrasulphide (40), and dithiasuccinimide (41), to yield the corresponding resin-bound thiophosphorylated peptide. 

Polymerization is carried out at 40°C and is allowed to continue until a 90% conversion is reached. The latex is cooled to 20°C and tetraethylthiuram disulphide is added the product is then allowed to stand for about 8 hours until the desired molecular weight is reached. The latex is then acidified with acetic acid just short of coagulation, which is ultimately accomplished by freezing on the surface of a cooled (about — 15°C) rotating drum partially immersed in the latex. The resulting film of polymer is stripped from the roll, washed, dried in air at 120°C and cut into small pieces. This method of isolation is used because polychloroprene is tacky and it is difficult to coagulate the latex directly to crumb. 

Stopped at about 91% conversion by the addition of a xylene solution of tetraethylthiuram disulphide. The emulsion is then cooled and aged for about eight hours during which time the polymer becomes peptized (solubilized, plasticized) by the action of the thiuram which also acts as a stabilizer for the finished product. The peptizing action of the thiuram is arrested by acidification of the latex which is then continuously coagulated on a freeze drum to produce the characteristic rope-like sections. 

In the same work it was noticed that pyrogallol (1,2,3-trihydroxy-benzene) was similarly effective if a sulphur donor such as MBTS, tetraethylthiuram disulphide or even elemental sulphur was present.

The methodology used in a study of nitrosamine formation in vulcanisation processes accelerated by tetraethylthiuram disulphide is described. This involved the characterisation of nitrosable species and the mechanisms of their formation, and studies of the influence of vulcanisation reactions and curing systems on the formation of nitrosable species. The results of the study are summarised.
