腈类化合物由于氮原子具有孤电子对,它可以和很多含有空轨道的金属卤化物配位生成分子配合物。Walton曾对乙腈、苯甲腈等腈类化合物与一些金属卤化物的分子配合物作过综述。文献亦曾报道脂肪族二腈与金属卤化物能形成配合物,而芳香族二腈和金属卤化物生成分子配合物则未见文献报道。此外,芳香族二腈在某些金属氯化物Lewis酸存在下,于300℃左右能进行聚合。为了探讨芳香族二腈在这些Lewis酸 Nitriles Because the nitrogen atom has lone pairs of electrons, it can coordinate with many metal halides containing empty orbitals to form molecular complexes. Walton has reviewed the molecular complexes of nitriles such as acetonitrile and benzonitrile with some metal halides. It has also been reported in the literature that aliphatic dinitriles and metal halides can form complexes, whereas aromatic dinitriles and metal halides have not been reported in the literature. In addition, aromatic dinitriles can polymerize at around 300 ° C in the presence of some metal chloride Lewis acids. In order to investigate aromatic dinitriles in these Lewis acids
