摘要 |
PROBLEM TO BE SOLVED: To provide a simple method for producing protocatechualdehyde in high yield by which the stirring properties during a reaction are improved without using toxic chlorine gas. SOLUTION: This method for producing the protocatechualdehyde represented by formula (2) is carried out as follows.
