WebThe mechanism of Grignard reagents is a bit elusive due to the inclusion of single-electron transfers, radical ions, surface-bound species, and perhaps even free radicals. 2 The R and Mg groups are covalently bond but extremely polarized, causing the R group to be a very powerful nucleophile. WebA 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 …
