RECYCLING OF ORGANOTIN COMPOUNDS

摘要

A method for the synthesis of a first organic molecule, said method comprising the steps of: a) Reacting a first reactant with an organotin reactant having at least one optionally substituted organic group having from 5 to 20 carbon atoms selected from alkyl, alkenyl, alkynyl, alkoxyalkyl, alkoxy, alkylthioalkyl, carboxylates and alkylaminoalkyl groups, thereby forming a mixture of a product and a tin-containing by-product, and b) Removing most of the tin-containing by-product from said mixture in such a way as to provide a purified product comprising less than 1000 ppm of remaining tin-containing by- product, wherein said step of removing most of said tin-containing by-product is either an extraction between a first liquid and a second liquid, said second liquid being more polar than said first liquid and at least partly immiscible therewith or is a reversed phase chromatography.
