The isolation and X-ray structure determination of an active intermediate in the accelerated sulfur vulcanization of alkenes
Abstract
In the sulfur vulcanization reaction of 2,3-dimethylbut-2-ene(C6H12), in the presence of S8, ZnO and organic accelerators, intermediate products are formed with consist of an alkene bound by sulfur to an accelerator fragment: C6H11–Sn–S(S)CNMe2, where n 0; the isolation characterisation and vulcanization activity of 2,3-dimethylbut-2-en-1-yl dimethyltrithiopercarbamate [C6H11–S–S(S)CNMe2] is described.
