General description
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.
Dimethylzinc is a diorganozinc reagent and nucleophile used in the synthesis of propargylic amines.
Application
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.

Developments in modern organic synthesis owe much to the field of radical chemistry. Mild reaction conditions, high selectivity, good functional group tolerance and high product yield are features that have made reactions involving radical species indispensable tools for synthetic chemists.
