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.
