Descrizione

Descrizione generale

SnCl₂ dihydrate reacts with acetic anhydride to yield anhydrous SnCl₂. SnCl₂ exhibits reducing properties in acidic media. SnCl₂ shows superior catalytic action in its molten state. It is a promising raw material for the chemical vapour deposition (CVD) of semiconducting layers. SnCl₂ participates in the reduction of aromatic nitro compounds, nitriles, cyanosilyl ethers and organic azides.

Applicazioni

Tin(II) chloride (SnCl₂) has been used as a starting material to evaluate the thermal behavior of SnCl₂ on heating at the rate of 5°Cmin^-1 in air. The product undergoes phase transformation on heating at rate of 5°C min^-1 in air, it involves an incomplete evaporation followed by oxidation forming SnO₂ nanoparticles. SnCl₂ has also been used for the fabrication of Sn-containing carbon nano-structures.

Tin(II) chloride may be used:

• To catalyze the addition of diazo sulfones, diazo phosphine oxides and diazo phosphonates to aldehydes to form β-keto sulfones, β-keto phosphine oxides and β-keto phosphonates, respectively.
• Along with trityl chloride, to catalyze the aldol reaction of silyl enol ethers with acetals or aldehydes and the Michael reaction of silyl enol ethers with α,β-unsaturated ketones.
• As a promoter in the allylic amination of allylic alcohols with amines in the presence of palladium catalyst.
