1,2-dihydroxy-3,5-diformylbenzene synthesis
- Product Name:1,2-dihydroxy-3,5-diformylbenzene
- CAS Number:116315-07-2
- Molecular formula:C8H6O4
- Molecular Weight:166.13
Yield:116315-07-2 50%
Reaction Conditions:
with trifluoroacetic acid at 80; for 5 h;
Steps:
1 Preparation of Example 1 Compound 2
Catechol and urotropine were refluxed at 80 °C for 5 hours under the condition of trifluoroacetic acid, and the reaction was completed by TLC detection. Dichloromethane and glacial acetic acid (150:1) were used as eluents to pass through silica gel chromatography column to separate. 4,5-dihydroxyisophthalaldehyde was obtained with a yield of 50%.
