Single electron transfer (SET)-photochemical decarboxylation of free carboxylic acids was performed in a polar solvent using several arenes such as phenanthrene, naphthalene, 1-methylnaphthalene, biphenyl, triphenylene, and chrysene in the presence of various electron acceptors such as 1,2-, 1,3-, and 1,4-dicyanobenzenes, methyl 4-cyanobenzoate, and 1,4-dicyanonaphthalene. The decarboxylation reaction was influenced by the arenes, electron acceptors, and solvent. The best result was achieved by the photoreaction using biphenyl and 1,4-dicyanonaphthalene in aqueous acetonitrile.
在极性溶剂中,通过单电子转移(SET)光化学脱羧反应对自由羧酸进行了研究,使用了多种芳香烃作为催化剂,例如菲、萘、1-甲基萘、联苯、三苯烯和苣烯,并在存在多种电子受体如1,2-、1,3-和1,4-二氰基苯、甲基4-氰基苯甲酸酯以及1,4-二氰基萘的情况下进行反应。脱羧反应受芳香烃、电子受体和溶剂的影响。最佳结果是通过在水合丙酮腈中使用联苯和1,4-二氰基萘进行光反应获得的。
