    摘要: A process for preparing amines comprises reacting an epoxide of the formula (I) where R1, R2, R3 and R4 are each, independently of one another, hydrogen or a linear or branched, saturated or unsaturated C2-C200-hydrocarbon radical, with ammonia and hydrogen in the presence of a catalyst, where the molar ratio of ammonia:epoxide is from 5:1 to 500:1 and the hydrogen pressure is from 10 bar to 500 bar.

    摘要: A process is described for preparing 3-trifluoromethylphenyl 4-cyanobenzyl ketone by reacting a C1-C2-alkyl 3-trifluoromethylbenzoate with 4-tolunitrile in an aprotic polar solvent or an aprotic polar solvent mixture in the presence of at least an equimolar amount of a base which is selected from potassium alkoxides of primary C1-C4-alkanols.
