| | Benzylidenemalononitrile Usage And Synthesis |
| Chemical Properties | SLIGHTLY YELLOW NEEDLE-LIKE CRYSTALLINE POWDER | | Uses | Benzylidenemalononitrile was used in fluorescence-based assay for determination of soluble methane monooxygenase activity in solution. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 49, p. 4819, 1984 DOI: 10.1021/jo00199a014
Tetrahedron Letters, 23, p. 4927, 1982 DOI: 10.1016/S0040-4039(00)85749-4 | | General Description | Benzylidenemalononitrile undergoes rapid and catalyst-free solid/vapor reaction with primary alkyl amines to yield N-benzylidene-amine. It undergoes addition reaction with octyl- and decylzirconocene chloride. It is a potential substrate for soluble methane monooxygenase. | | Synthesis | Benzaldehyde (1.0eq) was put into a 250mL round-bottomed flask, distilled water (100mL) was added as solvent, put into a clean stirrer, and then malononitrile (1.2eq) was added, and the reaction was placed at room temperature for 12 h. After the reaction was finished by TLC, a large amount of solid was precipitated, and it was filtered, and the cake was washed with petroleum ether, and the white solid product, benzylidene malononitrile, was dried. | | Purification Methods | Recrystallise the nitrile from EtOH [Bernasconi et al. J Am Chem Soc 107 3612 1985]. It has max at 307nm (EtOH). [Beilstein 9 H 895, 9 II 640, 9 III 4380, 9 IV 3462.] |
