Synthesis of naphthoquinone derivatives with some study on percentage rate of formation for pyridinium salt / Nor Shazana Mohamed Daud
The focus of this study is to synthesize the naphthoquinone derivative via the reaction of pyridinium salt with methyl naphthoquinone. The starting material 2,4-dibromoacetophenone reacted with pyridine to produce pyridinium salt in 96.29% yield. The further reaction was done, producing naphthoquino...
