Abstract
Tin tetra-alkoxides absent halogenic impurities are prepared by a two-step process comprising a first step reaction of tin tetrahalide with an alcohol and ammonia. A second step reacts the product of the first step with a metal amide and additional alcohol. An alternative second step reacts the product of the first step with a metal alkoxide.
