Paragraph: Reimer-Tiemann reaction introduces an aldehyde group, on to the aromatic ring of phenol, ortho to the hydroxyl group. This reaction involves electrophilic aromatic substitution. This is a general method for the synthesis of substituted salicylaldehydes as depicted below. Paragraph: Reimer-Tiemann reaction introduces an aldehyde group, on to the aromatic ring of phenol, ortho to the
