The Reimer–Tiemann reaction, an aromatic substitution reaction that occurs under basic conditions, is in many respects a unique reaction. It is one of the few organic reactions whose industrial importance seems to increase yearly, notwithstanding the environmental hazards associated with the use of ch...
Reimer–TiemannreactiontheoreticalstudyThe molecular mechanism for the pyrrole ring expansion to yield 3-chloropyridine, as a model of the abnormal Reimer–Tiemann rearrangement, was characterized theoretically in vacuo by means of the HF/6–31G* computational method. The electron correlation was ...
