Usage

Uses

1-[3-Chloro-5-trifluoromethylphenyl]-2,2,2-trifluoroethanone can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical production process.

Synthesis

Cool the solution containing compound III (74.4g, 0.255mol containing compound III) to -100, and add 120g of sulfuric acid with a mass fraction of 92.5% to the above system while keeping the temperature below 0. After acidification, continue to react and keep for 1.5h, and then add 126.7g of 33% sodium nitrite aqueous solution (containing diazotizing reagent sodium nitrite 0.612mol) into the system uniformly within 2h, and keep the temperature at 0 The following reaction is carried out for 2 hours, and the system is heated to room temperature after full reaction, 111.1 g of 50% hypophosphorous acid and 0.67 g of cuprous oxide are added, and the reaction is stirred for 2 hours while keeping temperature. After the reaction is over, stand to separate the layers, and wash the organic layer with a 5% sodium bicarbonate aqueous solution, dry with anhydrous magnesium sulfate, and rectify to obtain a clear and transparent oily liquid 1-[3-chloro-5-(trifluoromethyl) (Yl)phenyl]-2,2,2-trifluoroethanone 66.9, content 99.5%, yield 87.2%.

Method for synthesizing 3 -chloro -5 -trifluoromethyltrifluoroacetophenone

The invention discloses a method for synthesizing 3 -chloro -5 -trifluoromethyltrifluoroacetophenone, which comprises the following steps: firstly bromination and rechlorination of o-aminotrifluorotoluene to obtain 4 - bromo -2 - chloro -6 - trifluoromethylaniline. 4 - Bromo -2 - chloro -6 - trifluoromethylaniline was subjected to diazotization followed by treatment with hypophosphorous acid or ethanol to give the deamination compound 1 - bromo -3 - chloro -5 - (trifluoromethyl) benzene. 1 - Bromo -3 - chloro -5 - (trifluoromethyl) benzene was made into Grignard reagent with magnesium chips and reacted with the acylating agent to give 3 - chloro -5 - trifluoromethyltrifluoroacetophenone. The starting material ortho-aminotrifluorotoluene used in the route is a common chemical with cheap price, and the obtained product is high in purity and yield, relatively small in environmental pollution and expected to be used for large-scale industrial production.
