Popis

General description

tert-Butylmagnesium chloride, an organomagnesium compound, is commonly known as Grignard reagent. It is a powerful carbon nucleophile mainly used for C-C bond formation.

Application

tert-Butylmagnesium chloride (1.0 M in THF) has been used in the preparation of tert-butylsulfinyl chloride.
It can be used in:

• Grignard metathesis reaction of 2,5-dibromo-3-hexylthiophene to form 2-bromo-5-magnesiobromo-3-hexylthiophene.
• A key step for the asymmetric synthesis of sulfinyl transfer agents using cinchona alkaloids quinine and quinidine as chiral auxiliaries.

Other Notes

Storage below 25°C may cause formation of crystalline magnesium salts. Moving container to a warm location and ocassional gentle swirling should redissolve the solid.
