The present invention provides a production method of a 5-phthalancarbonitrile compound, which comprises the use of a novel compound of the formula [I]
1
wherein X is chlorine atom, bromine atom or iodine atom, as a key intermediate. The method of the present invention imposes small environmental burden (without use of a reagent imposing great burden on the environment, such as heavy metal, metal cyanide, thionyl chloride and the like) and is safe. The inventive method is based on a completely new strategy which is different from conventional production methods of 5-phthalancarbonitrile compound.
本发明提供了一种五苯并碳腈化合物的生产方法,其包括使用式子[I]中X为氯原子、溴原子或碘原子的新型化合物作为关键中间体。本发明的方法对环境的负担较小(不使用对环境造成很大负担的试剂,如重金属、金属氰化物、亚硫酰氯等),且安全。本发明的方法基于一种完全不同于传统五苯并碳腈化合物生产方法的新策略。
