टेट्रोक्साइड इसके अंग्रेजी अर्थ का उदाहरण

Osmium tetroxide (OsO4) is a popular oxidant used in the dihydroxylation of alkenes because of its reliability and efficiency with producing syn-diols.

Since osmium tetroxide is expensive and toxic, other metals have been used to prepare vicinal diols from olefins.

Typically, the ruthenium tetroxide is created in situ from ruthenium trichloride, and a secondary oxidant NaIO4 is used to regenerate the catalyst.

Manganese is also used in dihydroxylation and is often chosen when osmium tetroxide methods yield poor results.

The picture was obtained on a thin film of polymer cast onto mercury from solution, and then stained with osmium tetroxide.

Nitrogen tetroxide and UDMH were used as propellants.

The railcar contained dinitrogen tetroxide which was used as a process oxidant.

Lawsuits filed against Gaylord Chemical Corporation and Vicksburg Chemical (dinitrogen tetroxide supplier) were settled in May 2005.

In terms of raw material shopping, this taxol molecule consists of the aforementioned Wieland-Miescher ketone, 2-methyl-3-pentanone, lithium aluminium hydride, osmium tetroxide, phenyllithium, pyridinium chlorochromate, the Corey-Chaykovsky reagent and acryloyl chloride.

Two more hydroxyl groups were added by oxidation of the newly formed double bond with a catalytic amount of osmium tetroxide in the presence of N-methylmorpholine N-oxide.

Allylic alcohol 34, obtained from deprotection of silyl enol ether 33 with [acid], was oxidized with osmium tetroxide in pyridine to give triol 35.
