WitrynaCurrently, the chemistry of organofluorine compounds is a leading and rapidly developing area of organic chemistry. Fluorine present in a molecule largely determines its specific chemical and biological properties. This thematic issue covers the trends of organofluorine chemistry that have been actively developed in Russia the last 15 – … Witrynaorganic and pharmaceutical synthesis. An organomagnesium halide such as phenylmagnesium bromide (PhMgBr) is commonly referred to as a Grignard reagent. Other examples of organometallic compounds familiar from CHEM 343/345 include organolithium reagents (RLi) and lithium diorganocuprates (R 2 CuLi, Gilman reagents).
