WebThe Grignard reaction (French: ) is an organometallic chemical reaction in which alkyl, allyl, vinyl, or aryl-magnesium halides (Grignard reagent) is added to a carbonyl group in an … A Grignard reagent or Grignard compound is a chemical compound with the general formula R−Mg−X, where X is a halogen and R is an organic group, normally an alkyl or aryl. Two typical examples are methylmagnesium chloride Cl−Mg−CH3 and phenylmagnesium bromide (C6H5)−Mg−Br. They are a subclass of the organomagnesium compounds. WebFeb 7, 2024 · In preliminary experiments, the bis - (aryl)manganese reagent 1a was conveniently prepared by treating 4-bromoanisole ( 2a, 1.0 equiv.) in THF at −5 °C with magnesium turnings and LiCl (2.4 equiv.) in the presence of MnCl 2 (0.6 equiv.) within 1 h. Titration [ 31] with iodine led to a yield for 1a of 87%. format object powershell
