http://www.chem.ucla.edu/~harding/IGOC/G/grignard_reaction.html WebbA 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−CH 3 and phenylmagnesium bromide (C 6 H 5)−Mg−Br.They are a subclass of the …
WebbWith this said, the carbon atom in the epoxide is still partially positively charged which makes it an electrophilic center for the Grignard reagent. To summarize what we have discussed, the Grignard reaction works for compounds containing a carbonyl such as aldehydes, ketones, esters, nitrile, carbon dioxide and epoxides due to the ring strain.
