一般說明
Dimethylzinc (Zn(CH3)2) is a methylating reagent used to prepare methylated organic compounds as well as organometallic compounds containing methyl groups . It is also utilized as a reagent to prepare amino alcohols, oximes, and hydrazones from arylamines, alkoxyamines, and dialkylhydrazines respectively, by radical addition reaction in the presence of air and THF.
Dimethylzinc is a diorganozinc reagent and nucleophile used in the synthesis of propargylic amines.

應用
Dimethylzinc solution can be used as:
- A catalyst with nickel for the stereoselective C−2 alkenylation and dialkenylation of pyridine derivatives by alkynes to give monoalkenylation products.
- A reagent with aldehydes and 2-methoxyaniline for the synthesis of enantioselective alkyl and aralkyl secondary amines via one-pot three-component coupling reaction in the presence of zirconium tetraisopropoxide.
- A methylating reagent for methylation of fluoroalkylated pyruvates in the presence of copper/chiral diphosphine catalyst.
