Thermal Analysis of Nalidixic Acid Complexes with Cobalt (II), Vanadyl (II), Uranyl (II) and Ruthenium (III)
The thermal decomposition processes for metal complexes of nalidixic acid (NAL) viz: Co (NAL) OH , VO(NAL)2(H2O)3 , UO2 (NAL) 2(H2O)2 , Ru(NAL)2Cl(H2O) has been accomplished on the basis of TG, DTG and DTA studies, and the mechanism conforms to the stoichiometry of the complexes based on elemental analysis.
متن کاملThermal and Oxidative Degradation of Polymers
In recent decades synthetic polymeric materials, because of their unique physical properties, have rapidly replaced more traditional materials such as steel and nonferrous metals, as well as natural polymeric materials such as wood, cotton, and natural rubber. However, one weak aspect of synthetic polymeric materials compared with steel and other metals is that these materials are combustible u...
متن کاملPenicillin degradation catalysed by Zn(II) ions in methanol.
The rates of degradation, catalysed by Zn(2+), of four classical penicillins-amoxicillin, ampicillin and penicillins G and V-were followed at 20 degrees C in methanol by spectrophotometric assays. Kinetic schemes of the reactions of degradation catalysed by Zn(2+) ions were analogous to those given previously for the reaction catalysed by Cd(2+) ions. The methanolysis of penicillin V occurs wit...
متن کاملCobalt-catalysed Markovnikov selective hydroboration of vinylarenes.
A bipyridiyl-oxazoline cobalt catalyst tBuBPOCoCl2 has been developed for the Markovnikov selective hydroboration of alkenes using pinacolborane and NaOtBu as the in situ activator with up to >98 : 2 branched : linear selectivity (24 examples, 45-92% isolated yield).
متن کاملCobalt-catalysed asymmetric hydrovinylation of 1,3-dienes
In the presence of bidentate 1,n-bis-diphenylphosphinoalkane-CoCl2 complexes {Cl2Co[P P]} and Me3Al or methylaluminoxane, acyclic (E)-1,3-dienes react with ethylene (1 atmosphere) to give excellent yields of hydrovinylation products. The regioselectivity (1,4or 1,2-addition) and the alkene configuration (Eor Z-) of the resulting product depend on the nature of the ligand and temperature at whic...
