text: Fluorinations with DAST can be carried out in conventional glass equipment, although etching of the glass may result from reaction byproducts. Reactions are typically carried out in aprotic or non-polar solvents. Moisture and atmospheric oxygen should be excluded from the reaction. Reactions are generally started at -78 °C and warmed to room temperature or above; however, reactions should not be heated above 80 °C, as decomposition of the fluorinating reagent begins to occur at this temperature. Workup usually involves pouring the reaction mixture over water or ice, followed by neutralization of acidic byproducts with sodium bicarbonate. Standard purification methods can be used to isolate the desired fluorinated products.
