Synthesis of chiral thiourea ligands and their transition metal complexes
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: Modification of chitosan with benzoylisothiocyanate was attempted, however due to solvent problem the study was left incomplete till appropriate solvent is designed. N,N-diethyl-N -camphanoylthiourea ...
An Ab Initio density functional study of the structure and stability of transition metal ozone complexes
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: A thorough search through the literature as well as through the Cambridge Crystallographic Structural Database resulted in no examples of a neutral ozone acting as ligand in a complex with any metal. ...
Nuwe reaksies van gedeprotoneerde Fischer-tipe karbeenkomplekse
This study comprises the preparation and characterisation of completely new Fischer-type carbene complexes of chromium and tungsten by deprotonation of (CO)5M=C(NMe2)(Me), (CO)5M=C(OMe)(Me) or (CO)5M=C(NMe2)C≡CH, and ...
Synthesis and electrochemistry of biodegradable ligands - iminodiglutaric acid and iminoglutaricsuccinic acid - and their complexes with selected metal ions (Zn²⁺, Cd²⁺, Cu²⁺)
(Stellenbosch : Stellenbosch University, 2004-12)
ENGLISH ABSTRACT: Two new potentially biodegradable aminopolycarboxylic acid ligands, iminodiglutaric acid tetra sodium salt (IDG-4Na) and iminoglutaricsuccinic acid tetra sodium salt (IGS- 4Na), were synthesized in ...
A DFT study of the catalytic hydrocyanation of ethylene with nickel complexes
(Stellenbosch : Stellenbosch University, 2005-12)
ENGLISH ABSTRACT: DFT calculations employing the B3LYP functional were done to investigate the mechanism for the Ni-catalyzed hydrocyanation of ethylene as proposed by Tolman. Although this reaction is an important industrial ...
