Reactions of Halogenated α-Phenylcinnamic Acids with Potassium Amide in Liquid Ammonia : Part I - Reactions of cis- and trans-2-Chloro-α-phenylcinnamic Acids
Reaction of trans- and cis-2-chloro-α-phenylcinnamic acids (1) with KNH2 in liquid ammonia gives phenanthrene-9-carboxylic acids (2) and 3-phenylcarbostyrils (8).Under similar conditions 3-chloro-α-phenylcinnamic acids (5) furnish 3-phenylcoumarins (6).
