2373-51-5 Usage

Chemical Properties



Different sources of media describe the Uses of 2373-51-5 differently. You can refer to the following data:
1. Chloromethyl methyl sulfide is used as a methylene transfer reagent for iron(II) mediated cyclopropanation and for carbonyl and aromatic compounds. It protects alcohols as their methylthiomethyl (MTM) ethers by reaction, e.g. with NaH/NaI in DME. It is also used for the preparation of MTM esters of carboxylic acids, e.g. by treatment of the K salt of the acid in the presence of NaI and 18-crown-6 and for reaction with cyclopentadienyl iron dicarbonyl dimer in the formation of an iron-containing methylene transfer agent.
2. Methylthiomethylating reagent for carbonyl and aromatic compounds. Methylene transfer reagent for iron(II) mediated cyclopropanation.

Check Digit Verification of cas no

The CAS Registry Mumber 2373-51-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,7 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2373-51:
75 % 10 = 5
So 2373-51-5 is a valid CAS Registry Number.

New approach to the synthesis of linear and cyclic vinyl(alkoxy)siloxanes


, p. 1137 - 1142 (2017)

Main products of the reaction of vinyltrichlorosilane VinSiCl3 with DMSO in the medium of tetra-(alkoxy)silane are linear siloxanes (RO)3Si[OSiVin(OR)]OSi(OR)3, RO[Vin(RO)SiO]nSi(OR)3 (R = Me, Et, n = 0–2) and the hitherto unknown cyclic siloxanes [Vin(RO)SiO]m[(RO)2SiO]4–m (m = 1–3) formed in the ratio of 70: 30%. A tentative scheme of their formation is suggested with participation of the products of the alkoxy groups exchange between vinyl(alkoxy)dichloro-, vinyldi(alkoxy)chloro-, trialkoxychloro-, and dialkoxydichlorosilanes.

Matrix Isolation Investigation of the Vibrational and Electronic Spectroscopy and Photochemistry of Complexes of ClF and Cl2 with Sulfide Bases

Machara, Nicholas P.,Ault, Bruce S.

, p. 2046 - 2050 (1987)

Matrix isolation has been coupled with twin jet deposition for the formation of 1:1 molecular complexes of ClF and Cl2 with dimethyl sulfide and related bases.The infrared spectra of the complexes were dominated by an intense absorption which has been assigned to the perturbed halogen streching mode.This mode was greatly intensified and red-shifted upon complexes formation; the observed shifts of up to 300 cm-1 were much greater than shifts for the complexes of ClF with oxigen bases.The spectral differences have been rationalized in terms of hard/soft acid/base theory.Visible-ultraviolet spectra were also recorded for these complexes at high dilutions; for several an intense charge-transfer band was observed in the UV.Mercury arc irradiation into this charge-transfer absorption led to photochemically induced rearrangement reactions for several of complexes studied.

Reactions of alkali metal derivatives of metal carbonyls. VI. Some reactions of anions prepared from indenylmolybdenum tricarbonyl dimer and azulenedimolybdenum hexacarbonyl


, p. 475 - 481 (1965)

Indenylmolybdenum tricarbonyl dimer, [C9H7Mo(CO)3]2, is reduced by sodium amalgam in tetrahydrofuran to give a brown solution containing the [C9H7Mo(CO)2]- anion. This solution reacts with methyl iodide to form the expected yellow-orange tricarbonyl CH3Mo(CO)3C9H7. However, allyl chloride and chloromethyl methyl sulfide react with the [C9H7Mo(CO)3]- anion in tetrahydrofuran solution at room temperature to form the yellow dicarbonyls π-C3H5Mo(CO)2-C9H7 and π-CH3SCH2Mo(CO)2C9H7, respectively, in unusually facile decarbonylation reactions. Treatment of [C9H7Mo-(CO)3]2 with iodine in dichloromethane solution gives a brown dicarbonyl iodide C9H7Mo(CO)2I rather than the expected tricarbonyl iodide. Azulenedimolybdenum hexacarbonyl, C10H8Mo2(CO)6, reacts with sodium amalgam in tetrahydrofuran to give a yellow-brown solution which gives yellow dimeric [C10H8Mo(CO)3CH3]2 on treatment with methyl iodide.

DMSO as a Switchable Alkylating Agent in Heteroarene C?H Functionalization

Garza-Sanchez, R. Aleyda,Patra, Tuhin,Tlahuext-Aca, Adrian,Strieth-Kalthoff, Felix,Glorius, Frank

supporting information, p. 10064 - 10068 (2018/07/29)

Herein, we report a novel strategy for the activation of DMSO to act as a versatile alkylating agent in heteroarene C?H functionalization. This direct, simple, and mild switch between methylation/trideuteromethylation and methylthiomethylation of heteroarenes was achieved under reagent-controlled photoredox catalysis conditions. The proposed mechanism is supported by both experimental and computational studies.
