Usage

General Description

2,2'-[methylenebis(thio)]bis-Benzothiazole, also known as MBTS, is a chemical compound commonly used as a rubber additive in the manufacturing of tires and other rubber products. It acts as an accelerator, promoting the vulcanization process and improving the physical properties of the rubber, such as its tensile strength and resistance to heat and aging. MBTS is also used as a plasticizer and a corrosion inhibitor in various industrial applications. It is a pale yellow powder with a slight odor, and is considered to be relatively stable and non-toxic when handled and used properly. However, prolonged exposure to MBTS may cause skin and eye irritation, and it is important to use appropriate personal protective equipment when working with this chemical.

Infrared vibrations of carbon-sulphur bonds in bis(benzoxazole-, benzoimidazole-benzothiazole-2-thiol)methane. Assignments by "selenation"

The i.r. spectra of the title compounds have been compared with those of the corresponding-2-selenol derivatives.The i.r. vibrational assignments of the thioether links have been made on the basis of the selenation.The moiety CH2-(Y-CH2)2 (Y = S, Se) present in all the compounds considered gives typical absorptions in the fingerprint region.

Bromomethyllithium-mediated chemoselective homologation of disulfides to dithioacetals

An efficient, chemoselective homologation of disulfides and diselenides to the corresponding dithio- and diselenoacetals has been developed via the addition of bromomethyllithium. Chemoselectivity is fully preserved in the presence of concomitant electrophilic sites decorating the substrates. The synthetic potential of selected dithioacetals has been evaluated in Feringa-Fa?anas-Mastral-type Pd-catalyzed coupling with an organolithium and in the unusual 1,4-addition to a Weinreb amide.
