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 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 کاملPicture of a chelate in exchange: the crystal structure of NaHoDOTMA, a 'semi'-hydrated chelate.
Crystallography generally only provides static structural information. This can render it an ineffective technique for probing dynamic solution state processes. A crystal of HoDOTMA affords unique structures that effectively represent that of a lanthanide tetra-acetate chelate mid-way through the water exchange process.
متن کاملGadolinium chelate-associated nephrogenic systemic fibrosis.
Correspondence to: Dr Kei Pin Lin Tel: (65) 6222 3322 Fax: (65) 6326 5242 Email: binglin8@ yahoo.com.sg Nephrogenic systemic fibrosis (NSF) is a rare multisystem disease characterised by widespread tissue fibrosis. It is recognised for its epidemiological association in patients with chronic renal failure, after administration of gadolinium-chelate magnetic resonance (MR) contrast agent, partic...
