623-80-3 Usage

General Description

Dithiocarbonic acid S,S'-diethyl ester, also known as diethylthiophosphate, is a chemical compound used in the production of pesticides and herbicides. It is a colorless to yellow liquid with a garlic-like odor and is highly flammable. This chemical is known to be a potent inhibitor of acetylcholine esterase, which is an enzyme essential for nerve function. Due to its toxic and flammable nature, dithiocarbonic acid S,S'-diethyl ester is considered hazardous and must be handled with care, with proper protective equipment and ventilation in place during handling and storage.

Check Digit Verification of cas no

The CAS Registry Mumber 623-80-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 623-80:
(5*6)+(4*2)+(3*3)+(2*8)+(1*0)=63
63 % 10 = 3
So 623-80-3 is a valid CAS Registry Number.

Trithioorthoester Exchange and Metathesis: New Tools for Dynamic Covalent Chemistry

Bothe, Michael,Furlan, Ricardo L. E.,Orrillo, A. Gastón,Von Delius, Max

supporting information, p. 1988 - 1994 (2019/10/22)

To expand the toolbox of dynamic covalent and systems chemistry, we investigated the acid-catalyzed exchange reaction of trithioorthoesters with thiols. We found that trithioorthoester exchange occurs readily in various solvents in the presence of stoichiometric amounts of strong Bronsted acids or catalytic amounts of certain Lewis acids. The scope of the exchange reaction was explored with various substrates, and conditions were identified that permit clean metathesis reactions between two different trithioorthoesters. One distinct advantage of S, S, S-orthoester exchange over O, O, O-orthoester exchange is that the exchange reaction can kinetically outcompete hydrolysis, thereby making the process less sensitive to residual moisture. We expect that the relatively high stability of the products might be beneficial in future supramolecular receptors or porous materials.

Thiyl radicals in gas-phase thermolysis of xanthic acid esters

Deryagina,Korchevin,Russavskaya,Sukhomazova,Levanova

, p. 140 - 143 (2007/10/03)

Gas-phase thermolysis of xanthic acid esters and their reaction with acetylene at 250-600°C have been studied for the first time. The direction of the thermolysis is determined by the nature of the substituents at the oxygen and sulfur atoms. The main products of the thermolysis are gaseous hydrocarbons, carbon monoxide and hydrogen sulfide. The yields of liquid products of the thermolysis and of the reactions with acetylene are 4-46 %. The role of thiyl radicals in thiophene molecule formation and reaction routes to carbon disulfide, dithiocarbonates, and stilbene are discussed.

Thione-thiol rearrangement of xanthates catalyzed by pyridine N-oxides. Remarkably enhanced reactivity of 4-dialkylaminopyridine N-oxides

Harano,Nakagawa,Kamei,Kiyonaga,Hisano

, p. 1675 - 1682 (2007/10/02)

Pyridine N-oxides bearing electron-donating substituents (III) are efficient catalysts for rearrangement of O-alkyl S-methyl dithiocarbonates (xanthates) (I) to the corresponding S-alkyl S-methyl dithiocarbonates (dithiolcarbonates) (II). Of the catalysts tested, 4-piperidinopyridine N-oxide (IIIh) is the best from the viewpoints of catalytic activity and solubility in I. Heating of I in the presence of catalytic amounts (0.02-0.05 molar eq) of IIIh gave II together with the symmetric S,S-dialkyl and S,S-dimethyl dithiocarbonates in good yields. The catalytic behavior of donor-substituted pyridine N-oxides is discussed on the basis of kinetic and molecular orbital calculation data. The complete calculation of the perturbation equation on the initial stage of the reaction was consistent with the experimentally observed activity of the catalysts.
