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 کاملCooperative intramolecular interaction of diazacrown ether bearing beta-diketone fragments on an ionic liquid extraction system.
A novel extractant beta-diketone-substituted diaza-18-crown-6 demonstrated very efficient extraction of Sr(2+) due to an intramolecular synergistic effect on the ionic liquid extraction system and recovery of Sr(2+) from the ionic liquid was successfully achieved under acidic conditions.
متن کاملSteric and electronic influence on photochromic switching of N,C-chelate four-coordinate organoboron compounds.
A four-coordinate organoboron compound B(ppy)Mes(2) (1, ppy=2-phenylpyridyl, Mes=mesityl) was previously found to undergo reversible photochromic switching through the formation/breaking of a C-C bond, accompanied by a dramatic color change from colorless to dark blue. To understand this unusual phenomenon, a series of new four-coordinate boron compounds based on the ppy-chelate ligand and its ...
متن کاملSn(IV) Compounds Interaction with Metal-Schiff Base Complexes
The formation constants and Gibbs free energy for the interaction of RnSnClm (n = m = 2, R = Me, Ph, n-Bu or n = 4, m = 0, R = Ph) compounds as acceptors, with ML complexes (H2L = N,N'-bis(salicylidene)-2-aminobenzylamine (salabza-H2) and its derivatives, M = Mn2+ or Zn2+), as donors in N,N'-dimethylformamide (DMF) as solvent were studied. These parameters were measured by using UV-vis spectrop...
