Application

Tin(II) fluoride (SnF2) can be used:
  • As an inhibitor of Sn4+ in fabrication of formamidinium tin iodide (FASnI3) perovskite solar cells (PSCs) via SnF2–pyrazine complex formation.
  • As a catalyst in glycerol ketalization, Knoevenagel condensation and aldol-type reactions.
  • In the synthesis of α, β-epoxy ketone from α, α-dibromoacetophenone and aliphatic and aromatic aldehyde via oxidative addition of carbon-halogen bonds.
  • In the stereocontrolled [3 + 3] , [3 + 4], [3 + 5] annulations reactions.
