Dimethylzinc solution
Dimethylzinc solution (CAS: 544-97-8), with the linear formula (CH₃)₂Zn and a molecular weight of 95.46 g/mol, is a highly reactive organometallic compound. Supplied as a solution, typically 2.0 M in toluene, it is pyrophoric and reacts violently with water. It serves as a versatile reagent in organic synthesis, particularly for alkylation and in the formation of carbon-carbon bonds.
Organometallic Synthesis
Dimethylzinc is a key reagent for introducing methyl groups onto various substrates through alkylation reactions. Its high reactivity makes it valuable for forming new carbon-carbon bonds in complex molecule synthesis.
Precursor for Semiconductor Deposition
As an organometallic compound, it can be used in chemical vapour deposition (CVD) processes for the fabrication of semiconductor materials, although its pyrophoric nature requires specialised handling.
Reagent in Catalysis
It finds application in certain catalytic processes, often in conjunction with transition metals, to facilitate specific organic transformations. Its role can involve activating substrates or acting as a methylating agent.
