Participants

Reactant 2

HCID 23765Tributyltin iodide

HCID 522689Potassium Fluoride

Product 1

HCID 16120Tributyltin fluoride

Procedure

Bu3SnI will react on the column with KF to give Bu3SnF, which rapidly reacts with the silica. The purified product in ether is recovered and then dried on a vane pump. Bu3SnI+KFaq→Bu3SnF↓+Klaq
