A) 1-(2-Amino-5-chlorophenyll-1-(2-fluorophenyll-2-a2a-but-1-en-4-ol A mixture of 40 g of 2-methylimidazole hydrochloride and of 90 g of 2-amino-5-chloro-2 -fluoro-benzophenone in 240 ml of ethanolamine is heated at 135 for 2 hours. After cooling, the reaction mixture is poured into an aqueous sodium bicarbonate solution. The mixture is extracted with ether, the organic phase is washed repeatedly with water and is dried over sodium sulfate, and the solvent is evaporated to dryness. The residual oil is chromatographed on a silica column, elution being carried out with a 50/50 mixture of cyclohexane and ethyl acetate. 

IB) 1-(2-Amino-5-chlorophenyl)-1-(2-fluorophenyl)-3,3-bis-(ethoxycarbonyl)-2-a2a-prop-1-ene A mixture of 88 g of the product obtained above, 300 g of ethyl aminomalonate hydrochloride and 60 ml of acetic acid in 2.3 liters of absolute ethanol is heated to the reflux temperature for 6 hours. The alcohol and the acetic acid are evaporated in vacuo and the residue is taken up in ether. The solution is washed with a dilute sodium bicarbonate solution and... 

Samples of l,l,l-trifhioro-2,2-bis(p-fluorophenyl)-ethane, and the corresponding bis-(p-chlorophenyl) derivative were obtained by applying Henne s fluorination method to DFDT and DDT, respectively. In both instances a mixture of the mono-, di-, and trifluoro compounds was obtained, but the desired trifluorinated material was separated by fractional recrystallization from methanol and cooling with a mixture of dry ice and acetone.

From our research two compounds were selected from this group for marketing. They are the 0f-(2-chlorophenyl)-a-(4-chlorophenyl) (cmpd. 16) and 0f-(2-chlorophenyl)-0f-(4-fluorophenyl) (cmpd. 25) substituted 5-pyrimidine methanols, known as fenarimol and nuarimol, respectively. 

The 1,3,4-oxadiazole unit was initially incorporated into PAE in 1967 by reacting 2,5-di(4-fluorophenyl)-l,3,4-oxadiazole with bisphenol A [1]. The same route and same difluoro monomer were used more recently to prepare a series of polyfarylene ether l,3,4-oxadiazole)s [33]. The corresponding dinitro or di-chloro compounds, 2,5-di(4-nitro or chlorophenyl)-1,3,4-oxadiazole [33], were... 

Protox herbicides. A number of Protox herbicides share a 2-fluorophenyl group. Initial investigations into an alternative synthesis of 2-fluoro-4-chlorophenyl triazolinones resulted in the very promising use of newer fluorinating reagents. The actual synthesis of carfentrazone-ethyl involved the use of 2-fluoroaniline as the starting material (Fig. 35) [150],...
