-
Paragraph 0062-0071, (2020/06/16)
The invention relates to a preparation method of a monofluorobromoacetone derivative. The method comprises the following steps: mixing a compound as shown in a formula (1) with a catalyst, a ligand, alkali and a solvent, performing reacting with a compound as shown in a formula (2) under the protection of N2 until the reaction is complete, extracting and separating the obtained reaction solution to obtain the monofluorobromoacetone derivative as shown in a formula (3), wherein R1 is phenyl, substituted phenyl or heterocyclic ring; R2 is phenyl or substituted phenyl. Compared with the prior art, the method has the advantages of high reaction selectivity, milder conditions and shorter reaction time.

A palladium catalyzed Negishi-type α-arylation of α-fluoroketones with electron-rich and electron-deficient aryl halides or phenyl triflate has been developed. This direct mono-α-arylation method generate a variety of ternary α-aryl-α-monofluoroketones easily in good to excellent yields using XPhos as ligand and Cs2CO3as mild base.
