Grignard reagents are prepared by insertion ofbetween the carbon-halogen bond of alkyl and aryl halides. Grignard reagent or Grignard compound is a chemical compound with the generic 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 H. 3C−Mg−Cl and phenylmagnesium bromide (C. 6H.

The mechanism for this is quite complex, involving radical intermediates. Fortunately, this is NOT required at the undergrad orgo level. The most common and important Grignard reaction is the one with compounds containing a carbonyl group.

These reagents were revealed by the French chemist Victor Grignard, who won the Nobel Prize in Chemistry in the year 1912 for his work on these compounds. (i) Synthesis of hydrocarbon: Being hydrolyzed by water Grignard reagent forms hydrocarbons. RMgX + H 2 O → R – H + Mg (OH) X. Example: CH 3 MgI + H 2 O → CH 4 + Mg (OH) I. R-MgBr is referred to as a Grignard reagent.

Grignard reagents and water. Grignard reagents react with water to produce alkanes. This is the reason that everything has to be very dry during the preparation above. For example: The inorganic product, Mg(OH)Br, is referred to as a "basic bromide".
