Kinetic and synthetic investigation of the reactions os halogeno and arlyosycyclophosphazenes
The reaction of hexafluorocyclotriphosphazene, N?P?F? (14), with sodium phenoxide in THF yields phenoxy?substituted fluorocyclotriphosphazenes of all degrees of substitution. The results obtained in this investigation ... -
Kinetic studies on the interactions of gold (iii) with nucleic acids
The effects of the univalent ions like Li?, Na?, K?, Cs?, etc. and their counter ions on the CD spectra of various DNA samples have been investigated in some detail. With the increase in the concentration of the univalent ... -
Kinetics and mechanism of the transient behaviour of magnesium anodes
The main objective of the present investigation is to study the mechanism of delayed dissolution of magnesium anodes during discharge of magnesium dry cells. A supplementary part of the work is devoted to the development ... -
Lanthanide and actinide complexes of diphosphazane dioxides and lanthanide complexes of amino acids and peptides
The chemistry of f-block elements is currently undergoing rapid developments, and a rich and diverse chemistry is emerging because of its various applications (e.g., MOCVD precursors, MRI contrast agents). In addition, ... -
