General description

Tin (Sn) is a silvery-white metal that is malleable and ductile at ordinary temperatures. It is used as a catalyst in organic synthesis. It is also used in various sectors, such as nuclear energy, plastics, polymers, agriculture, biochemistry, and in glassmaking.

Application

Applied in the solid state synthesis of a Zintl phase, SrSn3Sb4, with an anionic channel framework of 30-membered rings.
Tin can be used in the following:      
  • With HCl, it reduces a variety of functional groups.
  • Stereoselective allylation of carbonyl compounds.     
  • In situ generations of tin enolates for directed aldol reactions.
  • Preparation of organotin reagents.
