Dimethyl sulfide (DMS) or methylthiomethane is an organosulfur compound with the formula (CH 3) 2 S.It is the simplest thioether and has a characteristic disagreeable odor. It is a flammable liquid that boils at 37 °C (99 °F).
Hydrogen peroxide is a typical oxidant—for example, with dimethyl sulfide (S(CH 3) 2): [9] S(CH 3) 2 + H 2 O 2 → OS(CH 3) 2 + H 2 O OS(CH 3) 2 + H 2 O 2 → O 2 S(CH 3) 2 + H 2 O. In analogy to their easy alkylation, sulfides bind to metals to form thioether complexes. Consequently, Lewis acids do not decompose thioethers as they do ethers ...
Thioether complexes feature pyramidal sulfur centers. Typical C-S-C angles are near 99° in both free thioethers and their complexes. The C-S distance in dimethylsulfide is 1.81 Å, which is also unaffected in its complexes. [5] The stereochemistry of thioether complexes have been extensively studied. [6]
The bond dissociation energies for dimethyl sulfide and dimethyl ether are respectively 73 and 77 kcal/mol (305 and 322 kJ/mol). Sulfides are typically prepared by alkylation of thiols. Alkylating agents include not only alkyl halides, but also epoxides, aziridines, and Michael acceptors. [6] They can also be prepared via the Pummerer ...
The general structure of an ether. R and R' represent most organyl substituents.. In organic chemistry, ethers are a class of compounds that contain an ether group—a single oxygen atom bonded to two separate carbon atoms, each part of an organyl group (e.g., alkyl or aryl).
In organic chemistry, a sulfone is a organosulfur compound containing a sulfonyl (R−S(=O) 2 −R’) functional group attached to two carbon atoms. The central hexavalent sulfur atom is double-bonded to each of two oxygen atoms and has a single bond to each of two carbon atoms, usually in two separate hydrocarbon substituents .
The structure of (CH 2 CH 2 S) 3 (9-ane-S3). In organic chemistry, thia-crown ethers are organosulfur compounds which are the thia analogues of crown ethers (cyclic polyethers). That is, they have a sulfur atom (sulfide linkage, −S−) in place of each oxygen atom (ether linkage, −O−) around the ring.
Dimethyl sulfone (DMSO 2) is an organosulfur compound with the formula (CH 3) 2 SO 2. It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). [4] This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert ...
