Usage

Uses

2-Chloro-1-(4-methylphenyl)-1-propanone is an intermediate for the synthesis of Mephedrone Hydrochloride (M224200), which is a stimulant drug related to cathinone and methcathinone. The effects of Mephedrone are reportedly comparable to those of similar drugs such as MDMA and methylone.

Access to α,α-dihaloacetophenones through anodic C[dbnd]C bond cleavage in enaminones

We have developed a method to synthesize α,α-dihaloketones under electrochemical conditions. In this reaction, the Cl- or Br- is oxidized to Cl2 or Br2 at the anode, which undergoes two-step addition reactions with the N,N-dimethyl enaminone, and finally breaks C[dbnd]C of the N,N-dimethyl enaminone to generate α,α-dihaloketones. The electrosynthesis reaction can be conveniently carried out in an undivided electrolytic cell at room temperature. In addition, various functional groups are compatible with this green protocol which can be applied simultaneously to the gram scale without significantly lower yield.

Production method of 2-(4-bromomethyl phenyl)propionic acid

The invention discloses a production method of 2-(4-bromomethyl phenyl)propionic acid. An adopted ionic liquid catalyst can be recycled and used, no molten aluminum trichloride is generated, a material does not need to be washed for multiple times, only layered extraction needs to be conducted, then a required product can be obtained, aluminum trichloride and triethanolamine salt ionic liquid is used, thus environmentally friendliness is achieved, the cost is also saved, and that is, an original cumbersome process is simplified. An original bromination reaction in a glass kettle is changed toa cooling glass pipeline circulation-type bromination reaction in the kettle, through the glass pipeline type reaction, the contact area of the material and light is increased, through circulation, the situation that the material is gathered on the illumination surface, and consequently light illumination is affected is avoided, thus the reaction efficiency is higher, the reaction time is shortened, the occurrence of a side reaction is controlled, and the product purity is higher.

Iodine(III)-Mediated Oxidative Hydrolysis of Haloalkenes: Access to α-Halo Ketones by a Release-and-Catch Mechanism

An unprecedented iodine(III)-mediated oxidative transposition of vinyl halides has been accomplished. The products obtained, α-halo ketones, are useful and polyvalent synthetic precursors. There are only a handful of reported examples of the direct conversion of vinyl halides to their corresponding α-halo carbonyl compounds. Insights into the mechanism and demonstration that this synthetic transformation can be done under enantioselective conditions are reported.
