| titleOfInvention | Method for Producing Aromatic and Heteroaromatic Carboxylic Acids, Carboxylic Acid Esters and Carboxylic Acid Amides |
| abstract | Process for the preparation of aromatic and heteroaromatic carboxylic acids, carboxylic acid esters and carboxamides by the reaction of aromatic or heteroaromatic halides R—X n , in which n=integer from 1 to 6, R=substituted or unsubstituted and aromatic or heteroaromatic radical and X=chlorine, bromine or iodine atom, with carbon monoxide and water, ammonia, alcohols or amines in the presence of bases and zero-valent or divalent palladium compounds and bidentate diphosphanes or complexes of zero-valent or divalent palladium with bidentate diphosphanes, in which use is made of bidentate diphosphanes n (R 1 —)(R 2 —)P—Y—P(—R 3 )(—R 4 )n n in which R 1 to R 4 =unsubstituted aryl radicals or aryl radicals substituted with at least one radical exhibiting a positive resonance effect or a positive inductive effect, or unsubstituted or substituted cycloalkyl radicals, and Y=hydrocarbon group with a total of 2 to 20 carbon atoms, in which at least one of the carbon atoms carries only one or no hydrogen atom as substituent; except for the reaction of 4-bromo-3-difluoromethyl-1-methylpyrazole with 2-(3,4,5-trifluorophenyl)aniline and carbon monoxide to give N-[2-(3,4,5-trifluorophenyl)phenyl]-3-difluoromethyl-1-methylpyrazole-4-carboxamide. |
