Abstract
Preparation of Styryl and Stilbenyl Derivatives of 1H‐Benzotriazoles1‐(p‐Tolyl)‐substituted 1H‐benzotriazoles react with anils of aromatic aldehydes in the presence of dimethylformamide and potassium hydroxide to yield the corresponding 1‐(styr‐4′‐yl)‐1H‐benzotriazoles and 1‐(stilben‐4′‐yl)‐1H‐benzotriazoles, respectively (‘anil synthesis’). Further, under the same reaction conditions, the Schiff's bases derived from p‐chloroaniline and 4‐(1′H‐benzotriazol‐1′‐yl)benzaldehydes give, with p‐tolyl‐substituted heterocycles, the corresponding heterocyclic substituted stilbenyl derivatives.
