13834-61-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13834-61-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,3 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13834-61:
(7*1)+(6*3)+(5*8)+(4*3)+(3*4)+(2*6)+(1*1)=102
102 % 10 = 2
So 13834-61-2 is a valid CAS Registry Number.

Oxoketene Dithiols: Synthesis of Some Heterocycles as Antimicrobials Utilizing Shrimp Chitin as a Natural Catalyst

Zayed, Salem E.,El-Maghraby, Awatef M.,Hassan, Entesar A.

, p. 1682 - 1698 (2014)

1, 2-dithiol 3-thione derivatives, as starting materials, were subjected to cycloaddition reactions in the presence of the dried outer shell of shrimp (chitin), under different reaction conditions to produce the 1, 3-dithiole-2-ylidene system. On treating 4-bromo dithiol 3-one, with dimethyl ester of acetylene dicarboxylic acid the bromo oxothiafulvene was produced. Further addition of DMAD to bromotrithiafulvene afforded the spiro bromo derivative. Trithiones and trithiafulvenes were also added to quinones, cyclohexadiene and cyclopentadiene monomer, and the corresponding adducts were produced through 1,3-dipole cycloaddition reactions. On testing some of the products against the isolated micro-organisms from sugar cane factory, the inhibition zones at concentration 1 × 10-6 were found. Products (2, 6, 9, 16, 23, 25, and 26) showed high activities against Bacillus sub., E.Coli and Asper. Niger.

Method for synthesizing 1,2-disulfide-3-thioketone derivative by using copper to catalyze

-

Paragraph 0030, (2019/06/12)

The invention relates to a method for synthesizing 1,2-disulfide-3-thioketone derivative by copper-catalyzed propargylamine sulfur cyclization, and the method comprises the following steps: N, N-dimethyl-3-phenyl propyl-2-alkynyl-1-amine is taken as a substrate, cuprous chloride, cuprous bromide or cuprous iodide is added into the substrate to serve as a catalyst, potassium phosphate, sodium bicarbonate or sodium acetate is taken as an alkali, elemental sulfur is taken as a sulfur source, stirring reaction is performed in a solvent for 12 hours at the temperature of 100-120 DEG C. The elemental sulfur is used as the sulfur source, and the method has the advantages of simple and easily available raw materials, simple reaction operation, relatively mild conditions, wide substrate universality, relatively high yield and good functional group compatibility.

1,2-dithio-3-thioketone derivative synthesized by cyclizing of fluorine-sulfur removal of trifluoropropyne via copper catalyzing

-

Paragraph 0042, (2018/11/03)

The invention discloses a 1,2-dithio-3-thioketone derivative synthesized by cyclizing of fluorine-sulfur removal of trifluoropropyne via copper catalyzing. The 1,2-dithio-3-thioketone derivative is prepared by the following steps of using a 2-chloro-3,3,3-trifluoro-1 propene compound as a primer; adding cuprous bromide as a catalyst into the primer, using cesium carbonate as alkaline, using tetramethylethylenediamine as a ligand, using elemental sulfur as a sulfur source, and stirring to react for 12 hours in a N,N-dimethyl formamide solvent at the temperature of 120 DEG C; after reaction is finished, filtering a reaction liquid, extracting a filtrate twice by a saturated sodium chloride solution, reversely extracting once, separating to obtain an organic phase, and drying with anhydrous sodium sulfate; filtering again, and removing the solvent out of the filtrate by a rotary evaporator, so as to obtain the remaining matter; performing column chromatography separating on the remainingmatter by a silicon gel column, spraying by an elution solution, and collecting an effluent solution containing the target product; combining the effluent solution, concentrating under the vacuum condition, and removing the solvent, so as to obtain the target product. The 1,2-dithio-3-thioketone derivative has the advantages that the raw materials are simple and are easy to obtain, the preparationtechnology is novel and simple, the pollution is little, the energy consumption is low, and the yield rate is high.

Switching Selectivity of α-Enolic Dithioesters: One Pot Access to Functionalized 1,2- and 1,3-Dithioles

Koley, Suvajit,Chanda, Tanmoy,Samai, Subhasis,Singh, Maya Shankar

, p. 11594 - 11602 (2016/12/09)

An operationally simple cascade protocol has been developed for the construction of 1,2- and 1,3-dithiole derivatives from α-enolic dithioesters. 1,2-Dithioles are achieved by the reaction of dithioesters with elemental sulfur in the presence of InCl3 under solvent-free conditions. 1,3-Dithioles have been constructed via DABCO mediated self-coupling of dithioesters in open air enabling the formation of two new C-S bonds and one ring in a single operation in contiguous fashion. The reactions proceeded smoothly affording the desired sulfur-rich heterocycles in good to excellent yields, exhibiting gram-scale ability and broad functional group tolerance utilizing easy to handle cheap and easily available reagents. The probable mechanisms for the formation of 1,2- and 1,3-dithioles from α-enolic dithioesters have been suggested.
