Abstract
1,271,754. Fluorinated diazonium compounds. KALLE A.G. 2 Sept., 1969 [3 Sept., 1968], No. 43401/69. Addition to 1,197,376. Heading C2C. [Also in Division G2] The parent Specification comprises diazonium compounds of the formula in which R 1 and R 2 denote alkyl, cycloalkyl or aralkyl groups or form a heterocyclic ring together with the nitrogen atom to which they are linked, R 3 denotes hydrogen or an alkoxy group or a fluorinated alkoxy group, R 4 and R 5 denote hydrogen or halogen atoms or alkyl, alkoxy or fluorinated alkoxy groups and X denotes an anion, at least one of R 4 and R 5 being hydrogen and at least one of R 3 , R 4 and R 5 being a fluorinated alkoxy group. This invention is now amplified to cover compounds of the formula above in which at least one fluorinated alkoxy group contains at least one fluorine atom attached to a carbon atom in α-position. The compounds may be prepared by processes analogous to known processes, a summary of which is given. Specific compounds are listed. The products are useful in diazotype photography (see Division G2). The preparation of the following intermediates is described. 1 - Methoxy - 4 - difluoromethoxybenzene is obtainable by reacting 4-methoxyphenol with difluorochloromethane in dioxane in the presence of sodium hydroxide. 6 - Nitro - 4 - methoxy - 3 - (methylbenzylamino)- α,α-difluoroanisole is obtainable by benzylating the corresponding unbenzylated secondary base. 4 - Chloro - 5 - nitro - 2 - acetylaminophenyl benzyl ether is obtainable by etherifying 4- chlorophenol with benzyl chloride, reducing the nitro group, acetylizing the resulting amino group, and further nitrating the product. 4 - Chloro - 5 - nitro - 2 - methylamino - α,α - difluoroanisole is obtainable by etherifying the corresponding phenol with difluorochloromethane in dioxane in the presence of potassium hydroxide.
