Definitions
- the invention relates to a method for nucleophilic substitution on activated aromatics of the general formula XIV
- Rl, R2, R3, R4 and R5 are the same or different and are a hydrogen atom, a nitro group, a cyano group, an alkoxycarbonyl group with up to 5 C atoms, an aldehyde group, an alkylcarbonyl group with up to 5 C atoms, an arylcarbonyl group or mean an amide group, where the radicals Rl to R5 cannot all be a hydrogen atom at the same time and HAL for a halogen atom, but especially a fluorine atom, with nucleophiles such as alcohols, amines, sulfoximides, CH-acidic compounds of the formulas V to XI
- HETN denotes an aromatic aza heterocycle with a total of 5 or 6 ring atoms, where up to 3 ring atoms can be nitrogen atoms and up to two further aromatic carbon rings may be fused to the heterocycle and Rl to R5 have the meaning given above.
- 1- (Benzotriazol-1-yl) -2, -dinitrobenzene can be obtained in 96% yield by boiling benzotriazole with 2,4-dinitrochlorobenzene in toluene for 9 days (A.R. Katritzky, J. Wu, Synthesis 1994, 597).
- 4-heterocyclically substituted nitrobenzenes and benzaldehydes can be obtained by reacting the respective aza heterocycles, e.g. Benzotriazole, 1, 2, 4-triazole or benzimidazole with 4-fluorobenzaldehyde or 4-fluoro- or 4-chloro-benzaldehyde can be obtained in DMSO or DMF at 100 ° C (DJ Gale, JFK Wilshire, Aust. J. Chem. 23, 1063, 1970; J. Rosevear, JKF Wilshire, Aust. J. Chem. 44, 1097, 1991).
- Benzotriazole, 1, 2, 4-triazole or benzimidazole with 4-fluorobenzaldehyde or 4-fluoro- or 4-chloro-benzaldehyde can be obtained in DMSO or DMF at 100 ° C (DJ Gale, JFK Wilshire, Aust. J. Chem. 23, 1063, 1970; J. Roseve
- Nitrophenylazoles can by Ullmann condensation of azoles with aryl halides in pyridine in the presence of potassium carbonate and copper (II) oxide at high temperatures and long reaction times (MA Khan, JB Polya, J. Chem. Soc. (C), 1970, 85; AK Khan , EK Rocha, Chem. Pharm.
- nucleophiles V to X also react with 2-fluoronitrobenzene at room temperature in the cesium carbonate / dimethylformide system: illustration 1
- R 1 to R 5 have the meaning given above and HAL stands for a halogen atom, but in particular for a fluorine atom, investigated in the system cesium carbonate / dimethyl formamide.
- dimethylformamide instead of dimethylformamide, other dipolar aprotic solvents such as e.g. Dimethylacetamide, acetonitrile, dimethyl sulfoxide, acetone or N-methylpyrrolidone can be used, but the reaction times at room temperature are then significantly longer and the yields are often lower.
- dipolar aprotic solvents such as e.g. Dimethylacetamide, acetonitrile, dimethyl sulfoxide, acetone or N-methylpyrrolidone
- the suspension is poured onto water, the product is extracted with ethyl acetate and the crude product obtained after evaporation of the organic phase is purified using the methods customary in organic chemistry, for example by crystallization or chromatography.
- the invention is illustrated and explained by the following exemplary embodiments:
- Example 9 N-2-cyanophenyldiphenylsulfoximide from 2 fluorobenzonitrile and diphenylsulfoximide at 80 ° C for 8 h / toluene -ethanol 10 + 1 / 74.3% / mp 160 ° C
- Example 10 N-2-cyanophenyldiphenylsulfoximide from 2 fluorobenzonitrile and diphenylsulfoximide at 80 ° C for 8 h / toluene -ethanol 10 + 1 / 74.3% / mp 160 ° C
- Example 10 N-2-cyanophenyldiphenylsulfoximide from 2 fluorobenzonitrile and diphenylsulfoximide at 80 ° C for 8 h / toluene -ethanol 10 + 1 / 74.3% / mp 160 ° C
