In Reimer - Tiemann reaction, phenol is converted into salicylaldehyde through an intermediate. The structure of intermediate is ______ .
  1. (A)(see structure)
  2. (B)(see structure)
  3. (C)(see structure)
  4. (D)(see structure)
    ✓ Correct

Answer: (D)

Solution

In the Reimer-Tiemann reaction, dichlorocarbene () attacks the ortho position of the phenoxide ring to give an ortho-substituted sodium phenoxide bearing a group. Hydrolysis of this benzal-chloride intermediate gives salicylaldehyde. The intermediate is the - sodium phenoxide, option (4).
