Electrochemical behaviour of some pyrimidine derivatives: polarographic reduction of 1, 3-dimethyl-2, 4, 6(1h, 3h, 5h) pyrimidinetrione and its substituted 5-phenylazo
(
Qatar University
, 1994 , Article)
The polarographic behaviour and spectrophotometric pKa of 1,3-dimethyl barbituric acid and 5-phenylazo substituted products were investigated in buffer solution of pH ~ 2-11. The results revealed an azo form of the substituted ...

Stereochemistry of some high coordination compounds of dioxouranium(VI) With thiosemicarbazones
(
Qatar University
, 1994 , Article)
The UO2 ion is peculiar in its coordination behaviour, because of its inherent capacity of forming compounds with higher coordination number. In the present work we describe the synthesis of a series of eight, nine and ten ...
