Preparation of Trifluoromethylphenyl Magnesium Halides in the Presence of LiCl and Synthesis of 2′-Trifluoromethyl-Aromatic Ketones

The effect of LiCl-promoted insertion of magnesium turnings into halogenated-trifluoromethylbenzenes for Grignard reagent synthesis was investigated. In the presence of less than 1.0 equiv of LiCl, chloro(trifluoromethyl)benzene Grignard reagents were easily generated. The 2-trifluoromethylphenyl magnesium chloride Grignard reagent was obtained in high yield and 2′-trifluoromethyl-substituted aromatic ketone was synthesized through reaction of the obtained Grignard reagent with a carboxylic anhydride in an 83% yield.

Formation of 2-trifluoromethylphenyl grignard reagent via magnesium-halogen exchange: Process safety evaluation and concentration effect

The thermal stability profile for a solution of 2-trifluoromethylphenyl magnesium chloride at 1.5Mconcentration in THF was determined using an Advanced Reactive System Screening Tool (ARSST). The solution generated by employing Knochel's magnesium-halogen

PROCESS FOR PRODUCTION OF BIPHENYL DERIVATIVES

A process for the production of biphenyl derivatives represented by the general formula (1), which is characterized by comprising reacting the chlorine atom of a benzene derivative represented by the general formula (2) with metallic magnesium to form a Grignard reagent and coupling two molecules of the Grignard reagent with each other in the presence of a catalyst and which is excellent in industrial productivity by virtue of its using inexpensive and easily available raw materials.
