[Hazard]

Flammable, dangerous fire and explosionrisk.
[Chemical Properties]

dark brown solution
[Application]

Methylmagnesium chloride solution (3 M in THF) undergoes 1,3-addition with dialdose derived nitrones to form N-benzylhydroxylamines. The reductive cleavage of the N-O bond of these N-benzylhydroxylamines results in N-benzylaminosugars, which are key moieties of bioactive compounds. It can also react with Garner type aldehydes to form the corresponding secondary alcohols.
[Preparation]

reaction of methyl chloride and magnesium in anhydrous diethyl ether, usually in the presence of an initiator.
[Reactions]

Methylmagnesium chloride can react with acidic hydrogen on oxygen, sulfur and alkyne carbon of compounds containing active hydrogen (such as water, alcohol, mercaptan, amine, amide, acid, sulfonic acid, etc.); Propyl bromide, etc.) undergoes a coupling reaction; it can react with oxygen and carbon dioxide, aldehydes, ketones, etc.
[reaction suitability]

reaction type: Grignard Reaction
