-
Paragraph 0079-0082, (2019/06/11)
The invention relates to a synthesis method for aromatic ring bromination of an acetophenones derivative, and belongs to the technical field of organic synthesis. The synthesis method consists of twokinds of synthesis methods: method A, adding the acetophenone derivative into a first oxidizing agent and stirring to form a suspension system, controlling the temperature of the suspension system tobe 10-50 DEG C, adding a first reducing agent or a second reducing agent, stirring and reacting for 2-20 h, and performing aftertreatment after the reaction is completed to obtain the aromatic ring brominated acetophenone derivative; method B, adding the acetophenone derivative into the second reducing agent and stirring to form a suspension system, controlling the temperature of the suspension system to be 10-50 DEG C, then adding a second oxidizing agent or the first oxidizing agent, stirring and reacting for 2-20 h, and performing aftertreatment after the reaction is completed to obtain thearomatic ring brominated acetophenone derivative. According to the synthesis method provided by the invention, an inorganic and non-toxic bromination reagent is used, water is used as a reaction solvent, the prepared product is mutually incompatible with water, so that separation and the aftertreatment are convenient to perform, therefore, the synthesis method of the invention is applicable to large-scale industrial production of intermediate products for aromatic ring bromination of the acetophenones derivative.

A variety of terminal alkenes were converted to the corresponding amides in yields of 25 to 86% in water via treatment with 1,3-dibromo-5,5-dimethylhydantoin, followed by reaction with molecular iodine and aq. NH3 (or amine) in one pot. This metal- and organic solvent-free protocol is not only suitable for styrene derivatives, but also, for the first time, works well on terminal aliphatic alkenes.
