Silver-Catalyzed C-H Trifluoromethylation of Arenes Using Trifluoroacetic Acid as the Trifluoromethylating Reagent

Direct trifluoromethylation of arenes using TFA as the trifluoromethylating reagent was achieved with Ag as the catalyst. This reaction not only provides a new protocol for aryl C-H trifluoromethylation, but the generation of CF3· from TFA may prove useful in other contexts and could potentially be extended to other trifluoromethylation reactions. (Chemical Equation Presented).

Process for producing trifluoromethylbenzylamines

The invention relates to a process for producing a trifluotomethylbenzylamine represented by the following general formula (1), 1where each R independently represents a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine, an alkyl group having a carbon atom number of 1-4, an alkoxy group having a carbon atom number of 1-4, an amino group, a hydroxyl group or a trifluoromethyl group, and n represents an integer from 0 to 4. The process includes hydrogenating a trifluoromethylbenzonitrile by hydrogen in an organic solvent in the presence of ammonia and a catalyst containing a platinum group element. This trifluoromethylbenzonitrile is represented by the following general formula (2), 2where R and n are defined as above. With this process, it is possible to obtain the trifluoromethylbenzylamine at an extremely high yield.

Process for producing trifluoromethylbenzylamines

The invention relates to a process for producing a trifluoromethylbenzylamine represented by the following general formula (1). This process includes hydrogenating a trifliuoromethylbenzonitrile represented by the following general formula (2) by hydrogen in an organic solvent in the presence of ammonia, using a Raney catalyst, where each R independently represents a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine, an alkyl group having a carbon atom number of 1-4, an alkoxy group having a carbon atom number of 1-4, an amino group, a hydroxyl group or a trifluoromethyl group, and n represents an integer from 0 to 4, where R and n are defined as above. With this process, it is possible to obtain the trifluoromethylbenzylamine easily and inexpensively at an extremely high yield.

Antimycotically active substituted 2-aminothiazoles

Antimicotically active 2-aminothiazoles have been found having the formula STR1 in which R1 represents hydrogen or alkyl and R2 represents optionally substituted cyclohexyl or phenyl which is substituted by halogen, alkyl, halogenoalkyl, halogenoalkoxy, dioxyhalogenoalkyl or halogenoalkylthio, and their physiologically tolerable acid addition salts, with the exception of the compounds 4-(4-chlorophenyl)-2-[2-(1,4,5,6-tetrahydropyrimidinyl)-amino]thiazole and 4-(2,4-dichlorophenyl)-2-[2-(1,4,5,6-tetrahydropyrimidinyl)-amino]-thiazole and 4-(4-chloro-2-methylphenyl)-2-[2-(1,4,5,6-tetrahydropyrimidinyl)-amino]-thiazole and with the exception of the physiologically tolerable acid addition salts of these compounds have been found.
