Preparation process of high-purity 3,5-bis(trifluoromethyl)benzyl alcohol

The invention discloses a preparation method of high-purity 3,5-bis(trifluoromethyl)benzyl alcohol, and belongs to the technical field of organic synthesis. The method comprises the steps: reacting a Grignard reagent generated by reaction of 3,5-bis(trifluoromethyl)bromobenzene and magnesium metal with a reagent capable of introducing an aldehyde group to obtain 3,5-bis(trifluoromethyl)benzaldehyde, and then reducing 3,5-bis(trifluoromethyl)benzaldehyde into 3,5-bis(trifluoromethyl)benzyl alcohol through sodium borohydride. The purity of the product obtained by the technical route is more than 99.5%, the maximum single impurity is not more than 0.1%, and the requirement on high-purity 3,5-bis(trifluoromethyl)benzyl alcohol in the market is met. Raw materials required by the process are easy to obtain, reaction conditions are mild, safety is high, production cost is low, and the method is suitable for industrialization.

Palladium-catalyzed arylation of aldehydes with bromo-substituted 1,3-diaryl-imidazoline carbene ligand

The combination of 0 valent palladium precursor and bromo-substituted 1,3-diaryl-imidazoline carbene ligand precursor such as 1-(2-bromophenyl)-3-(2,6-diisopropylphenyl)-imidazolinium chloride 1a exhibited high catalytic activity for the 1,2-addition of arylboronic acids to aldehydes including aqueous formaldehyde.

PROCESS FOR THE PREPARATION 3,5-BIS(TRIFLUOROMETHYL)BENZYLALCOHOL

The present invention concerns a process for preparing 3,5bis(trifluoromethyl)benzylalcohol by formylation in a solvent of an appropriate organo-magnesium derivative with solid paraformaldehyde and optionally its conversion into a 3,5-bis(trifluoromethyl)benzyl halide.
