Base-Free Suzuki acylation reactions of sodium (aryl trihydroxyborate) salts: a novel synthesis of substituted aryl ketones.
(2018)Asymmetric biaryl ketones are important building block in organic chemistry since they occur in large number of biological active compounds, natural product, cosmetics as well as in organic synthesis. The aim of this project ... -
Bioactive sesquiterpenoids from dicoma anomala subsp. gerrardii
(2008)Through South Africa’s first collaborative project between a large scientific organisation, the Council for Scientific and Indust rial Research (CSIR), and the Traditional Healer’s Committee, Dicoma anomala was identified ... -

(2015)Reactions of 2,6-bis((3,5-dimethyl-1H-pyrazol-1-ylmethyl)pyridine (L1) and 2,6-bis(3,5-dimethyl-N-pyrazolyl)pyridine (L2) ligands with Zn(II) and Cu(II), acetates and carboxylates (benzoates, 2-chlorobenzoate, & 2-bromobenzoate) ... -
Calibration techniques for 21-cm experiments with application to HERA: quasi-redundant calibration analysis.
(2018)Upcoming 21 cm observations promise to open a new window in our understanding of the universe from the epoch of recombination down to redshift of z 1. However, measurements of 21 cm signals come at a high cost since ... -
Capillary electrophoresis and related techniques for the analysis of fresh water algal toxins.
(1997)As cyanobacteria (also known as blue green algae) produce a range of cyclic peptides which are highly toxic, capillary electrophoresis and associated techniques have been investigated to assess their applicability ... -

The catalysed activation of n-octane over iron modified hydroxyapatites.
(2014)This research effort investigated the activation of n-octane by oxidative dehydrogenation and dehydrogenation over iron substituted and iron supported on hydroxyapatite catalysts. Pure hydroxyapatite and iron substituted ... -
Characterisation and quantification of wood extractives and their impact on pitch.
(2011)The aims of this study were to characterise and quantify wood extractives in E. grandis and E. nitens and determine the impact of wood extractives on pitch formation. Initially a comparison was made with individual solvent ... -
Characterisation of SAPPI SAICCOR pulp mill's effluent.
(2001)SAPPI SAJCCOR, whose factory is situated south of Durban, South Africa, is one of the few paper and pulp mills that uses the acid sulphite process with calcium and magnesium bases to produce a high-grade cellulose pulp. ... -
A chemical and pharmacological investigation of three South African plants.
(2006)Three plant species (Phylica paniculata Willd., Pergularia daemia Forssk. and Monsonia -
The chemical constituents of Ehretia rigida, Apodytes dimidiata and Ocotea kenyensis.
(1998)Three species have been investigated in this project: Iso-ocobullenone (p 23) and its probable precursor (p 27) have been isolated from the leaves and bark of Ocotea kenyensis. This is only the second time that these ... -
A chemical investigation of a KwaZulu-Natal medicinal plant, Momordica foetida Schum. & Sond.
(1994)Momordica foetida Schum. & Sond. (Cucurbitaceae), locally known as iNtshungu, is widely used by the Zulu people of Natal-KwaZulu for the treatment of a variety of ailments. The dried leaves leaves and stems of this plant ... -
