osmate การใช้

• The tetroxide and a related compound potassium osmate are important oxidants for chemical synthesis, despite being very poisonous.
• It can efficiently remove traces or excess amounts of chlorine, bromine, iodine, hypochlorite salts, osmate esters, chromium trioxide and potassium permanganate.
• For the Sharpless asymmetric dihydroxylation, which uses osmate for the conversion of a double bond into a vicinal diol, Karl Barry Sharpless won the Nobel Prize in Chemistry in 2001.
• It shares boundaries with Biandronno, Brebbia, Bregano, Cadrezzate, Comabbio, Ispra, Malgesso, Osmate, Ternate, and the pristine lake " Lago di Monate ".
• The cleavage of the exocyclic double bond was difficult and accomplished only with forcing conditions ( 19 equivalents of osmium textroxide, 105 癈, 24 hours ) by the putative osmate ester ( 45 ).
• Catalysts may affect the reaction environment favorably, or bind to the reagents to polarize bonds, e . g . acid catalysts for reactions of carbonyl compounds, or form specific intermediates that are not produced naturally, such as osmate esters in osmium tetroxide-catalyzed dihydroxylation of alkenes, or cause chemisorbed hydrogen in catalytic hydrogenation.
