On April 30, 1998, Gerstenberger, Ina; Hansen, Martin; Mauvais, Antony; Wartchow, Rudolf; Winterfeldt, Ekkehard published an article.Application of 5034-06-0 The title of the article was Regioselective and stereoselective transformations of enantiopure para-benzoquinone equivalents. And the article contained the following:

The selectivities of typical transformations of the 1,4-benzoquinone Diels-Alder adduct I (RR1 = bond) and its dihydro derivative I (R, R1 = H) are highly dependent on the mechanistic path followed. To avoid ambiguities and to make sure of clearly defined regioselectivity, 1,4-benzoquinone monoethylene ketal was examined and proven not only to be an excellent dienophile but, of course, also to lead to reliable regioselectivity in subsequent transformations. This led to the correction of an earlier provisional assignment of alkylation products. The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).Application of 5034-06-0

On April 10, 2002, Busch, Brett B.; Paz, Manuel M.; Shea, Kenneth J.; Staiger, Chad L.; Stoddard, Jonathan M.; Walker, James R.; Zhou, Xian-Zhi; Zhu, Huide published an article.Synthetic Route of 5034-06-0 The title of the article was The Boron-Catalyzed Polymerization of Dimethylsulfoxonium Methylide. A Living Polymethylene Synthesis. And the article contained the following:

Trialkyl and aryl organoboranes catalyze the polymerization of dimethylsulfoxonium methylide (1). The product of the polymerization is a tris-polymethylene organoborane. Oxidation affords linear telechelic α-hydroxy polymethylene. The polymer mol. weight was found to be directly proportional to the stoichiometric ratio of ylide/borane, and polydispersities as low as 1.01-1.03 have been realized. Although oligomeric polymethylene has been the most frequent synthetic target of this method, polymeric star organoboranes with mol. weights of 1.5 million have been produced. The average turnover frequency at 120° in 1,2,4,5-tetrachlorobenzene/toluene is estimated at >6 × 106 g of polymethylene (mol boron)-1 h-1. The mechanism of the polyhomologation reaction involves initial formation of a zwitterionic organoborane-ylide complex which breaks down in a rate-limiting 1,2-alkyl group migration with concomitant expulsion of a mol. of DMSO. The reaction was found to be first order in the borane catalyst and zero order in ylide. DMSO does not interfere with the reaction. The temperature dependence of the reaction rate yielded the following activation energy parameters (toluene, ΔH⧧ = 23.2 kcal/mol, ΔS⧧ = 12.6 cal deg/mol, ΔG⧧ = 19.5 kcal/mol; THF, ΔH⧧ = 26.5 kcal/mol, ΔS⧧ = 21.5 cal deg/mol, ΔG⧧ = 20.1 kcal/mol). The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).Synthetic Route of 5034-06-0

Ring-opening cyclization of cyclohexane-1,3-dione-2-spirocyclopropanes I (R = H, Me, Ph; R1 = H, Me; R2 = H, Ph, 4-methylphenyl, 4-bromophenyl, n-butyl; n = 1) using dimethylsulfoxonium methylide proceeded regioselectively to produce 2,3,4,6,7,8-hexahydro-5H-1-benzopyran-5-ones II (R3 = H; n = 1) in good to high yields. The reactions of cycloheptane- and cyclopentane-1,3-dione-2-spirocyclopropanes I (R = H; R1 = H; R2 = phenyl; n = 0 or 2) could construct [7.6]- and [5.6]-fused ring systems II (R3 = H; n = 0 or 2). This reaction was also carried out using triethyl(oxo)-sulfanylium chloride, tributyl(oxo)-sulfanylium chloride, and benzyldimethyloxo-sulfanylium chloride, resulting in the formation of the corresponding 2,3-trans-disubstituted products III (R4 = Ph; R5 = Me, Pr, phenyl) and II (R = H; R1 = H; R2 = H; R3 = Ph; n = 1) in good to high yields, and it was shown that the di-Me group can act as a dummy substituent. It was found that the 2- and 3-phenyhexahydrobenzopyran-5-ones II (R = H; R1 = H; R2 = H, phenyl; n = 1) can be readily converted into 5-hydroxyflavan and 5-hydroxyisoflavan, resp.

For studies of the conformation of nucleosides around the glycosyl linkages, the carbon-bridged cycloadenosines I (R = OH, R1 = H; R = H, R1 = OH) were prepared by the following route. Treatment of N6-benzoyl-2′,3′-O-isopropylideneadenosine 5′-aldehyde with dimethyloxosulfonium methylide afforded the 5′,6′-anhydrohexofuranosyladenine II, which was treated with thiophenoxide to give the diastereomeric 6′-phenylthio derivatives III. Photoirradiation of III followed by 5′-O-acetylation afforded III. Attempted synthesis of a 8,7′-cycloheptofuranosyl derivative by way of photolysis of a 7′-phenylthioheptofuranosyladenine resulted in the formation of 5′,6′,7′-trideoxy-2′,3′-O-isopropylidene-β-D-ribo-heptofuranosyladenine. The nature of the CD spectra of I is discussed. The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).Formula: C3H9ClOS

Jurga, Stefan published an article in 1980, the title of the article was Nuclear magnetic relaxation studies in solids.Recommanded Product: trimethyloxosulphonium chloride And the article contains the following content:

Spin-lattice relaxation times in the laboratory and in the rotating frame are reported for trimethyloxosulfonium fluoride, chloride, bromide and iodide as well as for Me2SO and Me2SO2 over a wide temperature range. A model was developed that makes it possible to analyze the exptl. data on the basis of 4 independent reorientations around 3 3-fold axis and around center of gravity . The following conclusions consistent with the 2nd moment and spin-lattice relaxation results are drawn about reorientational state of cations and mols. The Me group is reorienting about its 3-fold axis at random between 3 equilibrium positions separated by 120° in all the compounds A 3-fold reorientation of all cations around the C3 axis (designed by S → O bond) occurs. There is dynamical inequivalence of Me groups within the Me2SO mol. and trimethyloxosulfonium chloride with 1:2 ratio. There is observed translational diffusion in Me2SO2. The activation energies for C3 and C’3 reorientations decrease with an increase of an anion ionic radius (with exception of the iodide salt for the last motion).
