O-Difluorobenzene

The new method of Yoneda s group132 is also a one-pot diazotization-fluoro-de-diazoniation in a liquid-liquid two-phase mixture of pyridine and hydrogen fluoride. Yields for 25 aromatic amines and diamines are 50-100%, except for 2-and 3-fluorobenzoic acid, the three nitroanilines, 3- and 4-diaminobenzene and 4,4 -diaminodiphenyl-oxide (10-50%). In their 1994 paper the authors demonstrate that, in the same system, the photochemical decomposition gives in many cases significantly higher yields than the thermal reaction. The most spectacular increase in yield was found for the fluorination of 2-fluoroaniline where o-difluorobenzene was obtained photochemically in 80.2% yield, but thermally only in 0.6% ... [Pg.651]

Many applications of sodium and potassium organophosphides have been reported in the past year. The reaction of sodium diphenylphosphide with tosylates has been employed in the synthesis of steroidal phosphines. This reagent has also been used in the synthesis of a range of carbohydrate-derived phosphines, and in the synthesis of the phosphine (26), which can be linked to a silica support by treatment with acid. The reaction of sodium diphenylphosphide with o-difluorobenzene affords a convenient, one-pot synthesis of o-bis(diphenyl-phosphino)benzene. Sodium dimethylphosphide has been used to convert... [Pg.5]
