Zusammenfassung:	The invention refers to a process for preparing triphenyltrifluoropropanes and -propenes of formula III in which a 2-phenyl-3,3,3-trifluoropropiophenone derivative is reacted with bromobenzene under the conditions of the Grignard's reaction, and, if desired, a triphenyltrifluoropropane obtained is dehydrated to give a corresponding triphenyltrifluoropropane. The invention also refers to novel triphenyltrifluoropropanes and -propenes as well as novel 2-phenyl-3,3,3-trifluoropropiophenones used as intermediates. Procédé de préparation de triphényltrifluoropropanes et -propènes répondant à la formule (III), consistant à faire réagir un dérivé de 2-phényl-3,3,3-trifluoropropiophénone et du bromobenzène dans les conditions de la réaction de Grignard, et, le cas échéant, à déshydrater le triphényltrifluoropropane obtenu afin d'obtenir le triphényltrifluoropropène correspondant. L'invention concerne également de nouveaux triphényltrifluoropropanes et -propènes, ainsi que de nouvelles 2-phényl-3,3,3-trifluoropropiophénones utilisées comme intermédiaires.
