Definition of Dithiane. Meaning of Dithiane. Synonyms of Dithiane

- isomeric parent heterocycles are 1,2-dithiane, 1,3-dithiane and 1,4-dithiane. They are all colorless solids. 1,2-Dithiane is an organosulfur compound with...
- is converted into a dithiane or a thioacetal. In synthon terminology the ordinary carbonyl group is an acyl cation and the dithiane is a masked acyl anion...
- for acylation by converting aldehydes into lithiated 1,3-dithianes. The lithiated 1,3-dithianes serves as an acyl anion equivalent, undergoing alkylation...
- The formations of dithianes can be accomplished with a Lewis acid (scheme 7) or directly from carbonyl compounds. The pKa of dithianes is approximately...
- reversible formation of dithianes. A prototypical reaction is its formation of 1,3-dithiane from formaldehyde. The reactivity of this dithiane illustrates the...
- chemically. Therefore, a prodrug, sulfanegen sodium (2,5-dihydroxy-1,4-dithiane-2,5-dicarboxylic acid disodium salt), which hydrolyzes into 2 molecules...
- Benzene C6H6 ~49 Propene C3H6 ~44 Toluene C6H5CH3 ~43 Ammonia (N–H) NH3 ~41 Dithiane C4H8S2 ~39 Dimethyl sulfoxide (CH3)2SO 35.1 Diphenylmethane C13H12 32.3...
- acetylenes (H−CC−R), methyl sulfides (H−CH2SR), thioacetals (H−CH(SR)2, e.g. dithiane), methylphosphines (H−CH2PR2), furans, thiophenes and ferrocene (Fe(H−C5H4)(C5H5))...
- carbonyl group is protected with 1,3-propanedithiol 2, producing a dithiane 3. The dithiane is deprotonated using n-Butyllithium in tetrahydrofuran, and alkylated...
- referred to as umpolung. The reaction is commonly performed using the 1,3-dithiane. The lithiated intermediate can be used for various nucleophilic bond-forming...
