78887-70-4 - Introduction
pentadecylmagnesium bromide(pentadecylmagnesium bromide) is an organolithium compound with the chemical formula C15H31MgBr. It is a colorless to pale yellow liquid, often soluble in ether and petroleum ether.
pentadecylmagnesium bromide is mainly used in the field of organic synthesis as a reagent for the introduction of carbon anions. It can react with chloroalkyl, acid halide or acid anhydride to produce new organolithium compounds, which are often used to generate carbanions for substitution reactions, coupling reactions, condensation reactions, etc.
The common method for preparing pentadecylmagnesium bromide is to react bromoheptane and bromohexane with metal magnesium to generate the corresponding alkyl magnesium bromide salt, and then perform subsequent distillation to obtain the pentadecylmagnesium bromide.
During use, the pentadecylmagnesium bromide should be stored in dry, sealed and refrigerated conditions to prevent contact with moisture or oxygen in the air. It is a flammable substance that can produce flammable or explosive gases in contact with air, so it is necessary to take appropriate safety measures when handling, including wearing protective gloves, glasses and protective clothing, and maintaining a well-ventilated laboratory environment.
