Tetraallyltin Chemical Properties,Usage,Production

Chemical Properties

Clear Colorless liquid

Uses

Applied as allyl transfer reagent.

Purification Methods

Possible contaminants are allyl chloride and allyltin chloride. Check the 1H NMR and IR [Fishwick & Wallbridge J Organomet Chem 25 69 1970], and if impure, dissolve it in Et2O and shake it with a 5% aqueous solution of NaF which precipitates allyltin fluoride. Separate the Et2O layer, dry (MgSO4) and distil it at ~ 0.2mm. It decomposes slightly on repeated distillation. [O'Brien et al. Inorg Synth XIII 75 1972, Fishwick et al. J Chem Soc (A) 57 1971, Beilstein 4 III 1922.]
