Catalytic effects of metal chelate compounds.
This paper is essentially a progress report on the developments in the field of metal chelate catalysis since the first review of this subject fifteen years ago'. For the purpose of defining the scope of this field, metal chelate catalysis is considered to include any reaction that is altered or modified by metal ions through chelate ring formation, as well as reactions of metal chelates themse...
متن کاملThe Application of Chelate Compounds in Analytical Chemistry
The application of chelate reactions in a general way began a few years before the turn of the century, but the term 'chelate' was coined considerably later by Morgan and his colleagues at the University of Birmingham, who made the first systematic studies. Work in this field has continued at Birmingham for over half a century, apart from a break during the war years. During the last twenty-fiv...
متن کاملHyperpolarized [1,3-13C2 ]ethyl acetoacetate is a novel diagnostic metabolic marker of liver cancer.
An increased prevalence of liver diseases such as hepatitis C and nonalcoholic fatty liver results in an augmented incidence of the most common form of liver cancer, hepatocellular carcinoma (HCC). HCC is most often found in the cirrhotic liver and it can therefore be challenging to rely on anatomical information alone when diagnosing HCC. Valuable information on specific cellular metabolism ca...
متن کاملCatalytic, Enantioselective Aldol Additions with Methyl and Ethyl Acetate OSilyl Enolates: A Chiral Tridentate Chelate as a Ligand for Titanium(1V)
Asymmetric catalysis of the Mukaiyama aldol reaction has been reported with complexes derived from Al, B, Sn(II), and Ti(IV).l The levels of asymmetric induction for the addition of propionate-, isobutyrate-, and acetate-derived silyl thioketene acetals to aldehydes parallel those obtained with chiral-auxiliarybased methodologies.2 However, silyl ketene acetals derived from 0-alkyl acetates uni...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
