Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O ...
C 6 H 5 I + CH 3 CO 3 H + CH 3 CO 2 H → C 6 H 5 I(O 2 CCH 3) 2 + H 2 O. PIDA can also be prepared from iodosobenzene and glacial acetic acid: [5] C 6 H 5 IO + 2 CH 3 CO 2 H → C 6 H 5 I(O 2 CCH 3) 2 + H 2 O. More recent preparations direct from iodine, acetic acid, and benzene have been reported, using either sodium perborate [6] or ...
One variant of the reaction involves iminodiacetonitrile or iminodiacetic acid (step 1'), which reacts in a weakly acidic medium (pH 6) with hydrogen cyanide and ethanal to form methylglycinonitrile-N,N-diacetic acid, the nitrile group of which is hydrolyzed with sodium hydroxide to trisodium N-(1-carboxylatoethyl)iminodiacetate (step 2').
The compound was first prepared by the reaction of 3-(triethoxysilyl)propyl chloride with sodium tetrasulfide: [4] Na 2 S 4 + 2 ClC 3 H 6 Si(OEt) 3 → S 4 [C 3 H 6 Si(OEt) 3] 2 + 2 NaCl. Bis(triethoxysilylpropyl)tetrasulfide is a bifunctional molecule in that it contains two kinds of reactive functional groups.
(Bis(trifluoroacetoxy)iodo)benzene, C 6 H 5 I(OCOCF 3) 2, is a hypervalent iodine compound used as a reagent in organic chemistry. It can be used to carry out the Hofmann rearrangement under acidic conditions. [1]
Flames could be seen where a military helicopter made an emergency landing at Camp Pendleton on Friday, causing police to warn drivers of potential traffic delays along Interstate 5. All four crew ...
Neither the United States nor China would win a trade war, the Chinese Embassy in Washington said on Monday, after U.S. President-elect Donald Trump threatened to slap an additional 10% tariff on ...
In enzymology, a bis(5'-nucleosyl)-tetraphosphatase (asymmetrical) (EC 3.6.1.17) is an enzyme that catalyzes the chemical reaction. P 1,P 4-bis(5'-guanosyl) tetraphosphate + H 2 O GTP + GMP. Thus, the two substrates of this enzyme are P1,P4-bis(5'-guanosyl) tetraphosphate and H 2 O, whereas its two products are GTP and GMP.
