For example, Pinnick oxidation of thioanisaldehyde gives a high yield of carboxylic acid products, but with concomitant conversion of the thioether to the sulfoxide or sulfone.
22.
The reducing influence of the ethanol is apparent because the corresponding reaction in water affords fac-RhCl 3 ( pyridine ) 3, analogous to the thioether derivatives.
23.
Sulfur-containing substituents including linear thioether and sulfone, cyclic thiophene, thiadiazole and thianthrene are the most commonly used groups for increasing refractive index of a polymer.
24.
It is typically prepared, not by oxidation of the thioether, but by addition of sulfur dioxide to 1, 3-butadiene, followed by hydrogenation of the resulting sulfolene.
25.
Galactose oxidase is a thioether bond is believed to lower the oxidation potential of Tyr272 phenoxide, making this phenoxyl more easily oxidized to form the radical in post-translational modification.
26.
The unsaturated amino acids originate from serine and threonine, and the enzyme-catalysed addition of cysteine residues to the didehydro amino acids result in the multiple ( 5 ) thioether bridges.
27.
"' Lantibiotics "'are a class of peptide antibiotics that contain the characteristic polycyclic thioether amino acids lanthionine or methyllanthionine, as well as the 2-aminoisobutyric acid.
28.
Some compounds can considerably increase or decrease the solubility of AgX . Examples of compounds that increase the solubility include : cyanide, thiocyanate, thiosulfate, thiourea, amines, ammonia, sulfite, thioether, crown ether.
29.
Much effort is directed at functionalization of the corannulene ring with novel functional groups such as ethynyl groups, ether groups, thioether groups, platinum functional groups, aryl groups, phenalenyl fused and indeno extensions . and ferrocene groups.
30.
Thiol-ene reactions have been used alongside anhydride, esterification, Grignard, and Michael reactions to functionalize chain ends and build polymer backbones in the synthesis of branched molecules such as glycodendrons, poly ( thioether ) dendrimers and organosilicon thioether dendrimers.
