Modification of the Swern Oxidation: Use of Stoichiometric Amounts of an Easily Separable, Recyclable, and Odorless Sulfoxide That Can Be Polymer-Bound.

The Journal of organic chemistry

Liu Y, Vederas JC.
PMID: 11667743
J Org Chem. 1996 Nov 01;61(22):7856-7859. doi: 10.1021/jo961438d.

Readily available 6-(methylsulfinyl)hexanoic acid (1) is employed as a substitute for DMSO in Swern oxidation reactions using oxalyl chloride to smoothly convert primary or secondary alcohols to corresponding aldehydes or ketones in high yield. The resulting 6-(methylthio)hexanoic acid (2)...

Determination of sulfur compounds in hydrotreated transformer base oil by potentiometric titration.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry

PMID: 15984215
Anal Sci. 2005 Jun;21(6):721-4. doi: 10.2116/analsci.21.721.

A method was developed to analyze the distribution of sulfur compounds in model sulfur compounds by potentiometric titration, and applied to analyze hydrotreated transformer base oil. Model thioethers were oxidized to corresponding sulfoxides by tetrabutylammonium periodate and sodium metaperiodate,...

Virology. 1981 Aug;113(1):174-87. doi: 10.1016/0042-6822(81)90146-x.

Barley stripe mosaic virus (BSMV) RNA which was previously reported to contain poly(A) sequences (Agranovsky et al., 1978) can be specifically esterified with tyrosine in vitro in the presence of an aminoacyl-tRNA synthetase fraction from wheat embryos. All the...

Inhibition of Settlement by Larvae of Balanus amphitrite and Ciona intestinalis by a Surface-Colonizing Marine Bacterium.

Applied and environmental microbiology

Holmström C, Rittschof D, Kjelleberg S.

Appl Environ Microbiol. 1992 Jul;58(7):2111-5. doi: 10.1128/aem.58.7.2111-2115.1992.

In an attempt to isolate bacteria with inhibitory effects against settlement by larvae of sessile invertebrates, 40 marine bacterial isolates were screened for effects against laboratory-reared barnacle larvae (Balanus amphitrite) and ascidian larvae (Ciona intestinalis). Five isolates displayed non-pH-dependent...
