Steps

1
Handle and dispose organolithium reagents safely

Learn proper storage, transfer, and disposal procedures for organolithium reagents to prevent hazardous reactions with moisture and air. This section covers essential safety protocols before conducting any lithiation experiment.

3
Conduct lithiation reaction in glovebox

Perform the same lithiation in a controlled inert-atmosphere glovebox to eliminate air and moisture exposure. This method provides enhanced safety and reproducibility for sensitive organolithium reactions.
