(E)-1,2-bis(methylsulfanyl)ethene, also known as 1,2-bis(methylthio)ethene, is an organic compound with the chemical formula C4H8S2. It is a colorless liquid with a pungent odor and is characterized by its double bond between the first and second carbon atoms, with two methylsulfanyl (methylthio) groups attached to these carbons. This molecule is a member of the alkene class and exhibits a trans (E) configuration, meaning that the two methylsulfanyl groups are positioned on opposite sides of the double bond. It is used as a synthetic intermediate in the production of various organic compounds and has potential applications in the pharmaceutical and agrochemical industries. Due to its reactivity and potential health hazards, it is important to handle (E)-1,2-bis(methylsulfanyl)ethene with care and proper safety measures.

764-45-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 764-45-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 764-45:
(5*7)+(4*6)+(3*4)+(2*4)+(1*5)=84
84 % 10 = 4
So 764-45-4 is a valid CAS Registry Number.

Formation of symmetrical alkenes by homocoupling of metallated sulfones under nickel catalysis

Gai, Yonghua,Julia, Marc,Jean-Noe,Verpeaux

, p. 805 - 816 (2007/10/03)

Summary -Allylic sulfones undergo a coupling reaction with organometallic compounds (Mg or Li) not only with copper catalysts but also with iron or nickel salts. With 7,7-disubstituted allylic sulfones and also saturated aliphatic sulfones, however, another reaction was observed whereby two molecules of the starting sulfone are coupled to give symmetrical alkenes. The scope of this reaction was investigated. Elsevier.

Nucleophilic Substitutions of Unactivated Vinyl Halides with Alkanethiolate Anions in Hexamethylphophoramide

Tiecco, Marcello,Testaferri, Lorenzo,Tingoli, Marco,Chianelli, Donatella,Montanucci, Manuela

, p. 4795 - 4800 (2007/10/02)

The reactions of unactivated vinyl halides with the sodium salts of alkanethiols in HMPA gave vinyl alkyl sufides in high yields.These reactions occur with complete retention of configuration.With di-, tri-, and tetrachloroethylenes all the chlorine atoms are substituted by alkylthio groups.By treatment with alkanethiolates the vinyl sulfides are dealkylated to give the sodium salts of the ene thiols.By reaction with sodium all the alkylthiogroups present in the molecule suffer fragmentation to give the sodium salts of the corresponding mercaptoethylenes.

PHOTOCHEMICAL REACTIONS OF 2-BORNANETHIONE (THIOCAMPHOR) WITH BIS(METHYLTHIO)ETHYNE. ADDITION AND INTRAMOLECULAR HYDROGEN ABSTRACTION

Brouwer, A. C.,Bos, H. J. T.

, p. 103 - 109 (2007/10/02)

Irradiation of a mixture of bornanethione 7 and bis(methylthio)ethyne 2a afforded a mixture of methyl E- and Z-2-(2-bornylidene)-2-(methylthio)ethanedithioate 8 and E-1,2-bis(methylthio)vinyl 2-bornen-2-yl sulfide 10E.The first compounds are the products of the (2+2)-photocycloaddition reaction between bornanethione 7 and acetylene 2a.The sulfide 10E is rationalised as being the product of an intramolecular H abstraction reaction of the 1,4-biradical 12 which is also believed to be the intermediate in the (2+2)-cycloaddition reaction.
