Tin(IV) chloride
Tin(IV) chloride (CAS 7646-78-8), with the molecular formula SnCl₄ and a molecular weight of 260.52 g/mol, is a fuming, colourless liquid. It acts as a potent Lewis acid and is extensively employed in organic synthesis, particularly in Friedel-Crafts reactions and as a catalyst. Its ability to form coordination complexes also makes it valuable in materials science and as a precursor in the deposition of tin oxide films.

Lewis Acid Catalyst
Tin(IV) chloride serves as a strong Lewis acid catalyst in various organic transformations. It is particularly effective in catalysing Friedel-Crafts acylation and alkylation reactions, facilitating the formation of carbon-carbon bonds.
Chemical Synthesis Reagent
It is widely used as a synthetic reagent in the production of organotin compounds and other tin-based chemicals. Its reactivity allows for diverse synthetic pathways in both laboratory research and industrial processes.
Precursor for Tin Oxide Films
Tin(IV) chloride is a key precursor in chemical vapour deposition (CVD) processes for producing thin films of tin dioxide (SnO₂). These films are vital for applications in transparent conductive coatings and gas sensors.
Chlorination Agent
In specific synthetic contexts, SnCl₄ can act as a chlorinating agent, introducing chlorine atoms into organic molecules. This property is leveraged in the synthesis of complex organic structures.
