General description

4-Cyanobenzoyl chloride participates in the benzylamine acylation of Argopore MB-CHO resin in the presence of pyridine and catalyst. It reacts with 4-hydroxy-2,2,6,6-tetramethyl-1-piperidinoxyl (4-hydroxy-TEMPO) in pyridine under nitrogen atmosphere to form 4-cyanobenzoyl-TEMPO.

Application

4-Cyanobenzoyl chloride has been used in the synthesis of new liquid crystalline heteroaromatic compounds containing the five-membered isoxazole, tetrazole and 1,2,4-oxadiazole rings. It has been used in the synthesis of substituted benzoate esters and to study their excited-state behavior.

Anion complexation properties of two new tripodal amide receptors have been extensively studied here. Two tripodal receptors have been synthesized from the reaction of cyanobenzoyl acid chloride with two tri-amine building blocks such as (i) tris(2-aminoethyl)amine and (ii) tris(2-(4-aminophenoxy)ethyl)amine, which
