Bis (monoalkyltin) orthosulfites, of the formula WHEREIN R is an alkyl preferably having one to 12 carbon atoms and Z is hydroxy or a monovalent or divalent organic radical bonded to the tin through an oxygen or sulfur atom and can be prepared by oxidation of monoalkylthiostannoic acids with organic hydroperoxides, optionally followed by condensation with various functional groups. These novel orthosulfites are useful as condensation, polycondensation and polymerization catalysts; as fungicides, bactericides and stabilizers for synthetic polymers.
