Thermal investigations on arylmercury(II) complexes of kojic acid and maltol
摘要:
Arylmercury(ll) derivatives of kojic acid and maltol of the type pXC(6)H(4)HgL(1) (I) and p-XC(6)H(4)HgL(2) (II) [HL(1)=kojic acid, HL(2)=maltol; X=M, MO, NO2] have been synthesised. IR spectral studies indicate that both the ligands act as bidentate groups, bonding to the mercury(II) ion through phenolic and carbonyl oxygens. From TG curves, the order and activation energy of the thermal decomposition reaction have been elucidated. The variation of the activation energy has been correlated with the nature of the substituents on the phenyl ring. The heat of reaction has been elucidated from differential scanning calorimetric studies. The fragmentation pattern has been analysed on the basis of mass spectre.[GRAPHICS]P>-1.
