WebIron(III) tosylate is an inexpensive and readily available catalyst. The use of water, the most environmentally benign solvent, makes this procedure especially attractive for acetal deprotection. AB - The deprotection of aromatic as well as conjugated acetals and ketals in water is catalyzed by iron(III) tosylate (1.0-5.0 mol %). WebTosylate is an anion which is derived from tosilic acid. Structurally, it is a toluene having sulfonate group connected at the 4th position. An organic tosylate is created alternatively by transforming an alcohol group (OH) into sulfonic ester using compounds such as para-toluene sulfonyl chloride ( \text {Ts}-\text {Cl}) (Ts −Cl). share the dignity brisbane

WebJul 1, 2006 · The oxidants were dissolved in the ionic liquid and added dropwise, with stirring, to the monomers dissolved in the ionic liquid. Terthiophene, iron tosylate and silver nitrate all required heating to ca. 50 °C in the ionic liquid to achieve dissolution.The concentrations given in Table 1 are the concentrations of the reagents in the total reaction … In organic chemistry, a toluenesulfonyl group (tosyl group, abbreviated Ts or Tos) is a univalent functional group with the chemical formula −SO2−C6H4−CH3. It consists of a tolyl group, −C6H4−CH3, joined to a sulfonyl group, −SO2−, with the open valence on sulfur. This group is usually derived from the compound tosyl chloride, CH3C6H4SO2Cl (abbreviated TsCl), which forms esters and amid… WebOn 29 May 1890 the wooden-hulled propeller W.R.
