| | 4-Cyanobenzoyl chloride Usage And Synthesis |
| Chemical Properties | almost white to beige crystalline powder | | Uses | 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. | | Definition | ChEBI: 4-cyanobenzoyl chloride is an acyl chloride consisting of benzoyl chloride in which the hydrogen at position 4 is replaced by a cyano group. It is a nitrile, a member of benzenes and an acyl chloride. It is functionally related to a benzoyl chloride. | | 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. | | Purification Methods | If the IR shows the presence of OH, then treat it with SOCl2 boil for 1hour, evaporate and distil it in a vacuum. The distillate solidifies and can be recrystallised from pet ether. It is moisture sensitive and an IRRITANT. [Ashley et al. J Chem Soc 103 1942, Fison et al.
