Efficient photocyanation of various arenes with sodium cyanide in 9:1 acetonitrile–water occurs in the presence of such electron acceptors as p-dicyanobenzene, 1-cyanonaphthalene, or 9-cyanophenanthrene. Under nitrogen, photocyanation of phenanthrene, anthracene, naphthalene, and 2,3-dimethylnaphthalene gives both the corresponding hydrocyanation products and the aromatic nitriles, while complex mixtures
在存在诸如对二氰基苯,1-氰基萘或9-氰基菲等电子受体的情况下,使用氰化钠在9:1的乙腈-水中对各种芳烃进行有效的光氰化。在氮气下,菲,蒽,萘和2,3-二甲基萘的光致氰化反应既产生相应的氢氰化产物,又产生芳族腈,同时与其他芳烃形成复杂的混合物。在氧气下,自然界中各种电子供体的芳烃经辐照可以有效地氰化,得到芳族腈。萘衍生物的氰化仅产生1-氰基萘化合物,而菲和蒽在C-9处氰化。
