Document Type and Number:
WIPO Patent Application WO/2021/174748
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a visible light catalyzed dichlorine addition product of an aliphatic olefin, comprising the following steps: using an aliphatic olefin as a substrate, using copper chloride having visible light absorption capacity as a catalyst, and using hydrochloric acid as a chlorine source, performing a reaction in an organic solvent under irradiation of visible light, the reaction being carried out in an oxygen atmosphere, and after the reaction is completed, obtaining a dichlorine addition product of the aliphatic olefin. The aliphatic olefin comprises a carbon-carbon double bond and a C9-C15 aliphatic chain linked by a covalent bond to the carbon-carbon double bond. The present invention uses visible light to provide energy required for a reaction, uses a transition metal chloride having visible light absorption capacity to generate light-induced chlorine atom transfer with a reaction substrate to initiate an addition reaction, so as to obtain a dichlorine addition product. The method of the present invention has mild reaction conditions, simple and convenient operation, and wide applicability of the reaction substrate.
