6-Hydroxy-2-naphthaldehyde Usage And Synthesis
Synthesis
A stirring bar, 0.35 g (2.01 mmol) of 6-hydroxy-2-naphthylcarbinol and 20 mL of N, N-dimethylformamide were introduced into a 100 mL flask to form a homogenous mixture. This mixture was added with 3.5 g (36.94 mmol) of electrolytic manganese dioxide (FMH, Tosoh, purity: 91.77 per cent) and vigorously stirred for 16 hours while the mixture was maintained at 20°C. The reaction mixture was analyzed by using liquid chromatography. As a result, it was found that the conversion of the 6-hydroxy-2-naphthylcarbinol was 92.3 per cent, and the yield of the 6-hydroxy-2-naphthaldehyde was 87 percent.
