摘要：PROBLEM TO BE SOLVED: To provide new 1,1,3,3-tetrafluoro-1H,3H-naphtho[1,8-c,d]-pyran compounds which are useful intermediate compounds expected of utilization for producing an organic fluorescent substance, a dye, etc., and a method for producing the compounds. SOLUTION: A 4-halogeno-1,8-naphthalic acid as a raw material is passed through a new 1,1,3,3-tetrafluoro-6-halogeno-1H,3H-naphtho[1,8-c,d]pyran, new 1,1,3,3-tetrafluoro-6-methyl-1H,3H-naphto[1,8-c,d]-pyran and a new 1,1,3,3- tetrafluoro-6-halogenomethyl-1H,3H-naphtho-[1,8-c,d]pyran to produce the 1,1,3,3- tetrafluoro-6-cyanomethyl-1H,3H-naphtho[1,8-c,d]pyran.
