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