General description

Tin is an efficient catalyst for the polycondensation of lactic acid to synthesize poly(lactic acid).

Application

With HCl, reduces a variety of functional groups; stereoselective allylation of carbonyl compounds; in situ generation of tin enolates for directed aldol reactions.

The kesterite-structured semiconductors Cu2ZnSnS4 and Cu2ZnSnSe4 are drawing considerable attention recently as the active layers in earth-abundant low-cost thin-film solar cells. The additional number of elements in these quaternary compounds, relative to binary and ternary semiconductors, results in increased flexibility
