Description

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.
