Takahashi, Yusuke; Seki, Masahiko published an article in 2021. The article was titled 《Finkelstein Reaction in Non-polar Organic Solvents: A Streamlined Synthesis of Organic Iodides》, and you may find the article in Organic Process Research & Development.Electric Literature of C7H13BrO2 The information in the text is summarized as follows:
The Finkelstein reaction of organic halides was found to proceed smoothly in non-polar organic solvents other than acetone when operated in the presence of a catalytic amount of tetra-n-butylammonium bromide and water. The new protocol was successfully applied to a preparation of Et 5-iodopentanoate from the corresponding bromide which was used directly for zinc reagent formation and Fukuyama coupling to enable the formation of the (+)-biotin side chain in a streamlined manner. Rate acceleration by microwave irradiation and an application to the synthesis of trimethylsilyl iodide was described as well. In the experiment, the researchers used Ethyl 5-bromovalerate(cas: 14660-52-7Electric Literature of C7H13BrO2)
Ethyl 5-bromovalerate(cas: 14660-52-7) belongs to bromides. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact.Electric Literature of C7H13BrO2
