What is Tetraallyltin?
Chemical properties
Clear Colorless liquid
The Uses of Tetraallyltin
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.]
