애플리케이션

Dimethylzinc 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 enantioselective synthesis of alkyl and aralkyl secondary amines via one-pot three-component coupling reaction in the presence of zirconium tetraisopropoxide.
• A methylating reagent for the methylation of fluoroalkylated pyruvates in the presence of a copper/chiral diphosphine catalyst.
• An activator for radical trifluoromethylation of silyl enol ethers leading to α-trifluoromethyl ketones.
