Study on synthesis bromination derivatives of polyethylene glycol monomethyl ether;

Comparing to different reaction methods, the method starting from 1,3-dimethyladamantane was certified with the memantine hydrochloride synthesized by bromination ,acetimidolation, hydrolysis and acidation.

Bromacil was synthesized using 2-bromobutane and urea as the starting materials in three steps including condensation,cyclization and bromination with total yield of 61%.

The Study on Bromization of Benzene on the Platinum Electrode By Confocal Microprobe Raman Spectroscopy;

Suzuki cross-coupling reactions between aryl bromides and phenylboronic acids were studied over a hydroxyapatite-supported Mn catalyst(MnHAP) for the first time.

The palladium catalyst supported on fluoride pillared layered double hydroxide(LDH-F) was prepared by the incipient wetness method,and it was used to catalyze the Heck and Suzuki coupling reactions of aryl bromides.

6 were obtained from thioamides and α-bromoketones by a four-step reaction.

Quinoxalines were obtained from α-bromoketones,1,2-diaminobenzene and DMSO in a solvent-free one-pot process at room temperature under grinding.

On the basis of this, the additionreactions of N-sulfonylimines with α-bromoketones and α-bromoesters in the presentof zinc powder were carried out.
