Superbase metalation of alkenes or alkylbenzenes and subsequent condensation with trialkylstannyl chloride affords allyl- or benzyl-type organotin compounds that can be isolated in pure form.Treatment with soluble reagents such as methyllithium, trimethylsilylmethylpotassium and trimethylsilylmethylcaesium generates the corresponding organoalkali derivatives almost quantitatively and in high purity, suitable for kinetic or spectroscopic studies.
