Abstract

Tributyltin compounds have been successfully used for many years as wood preservatives, although their chemical nature in timber has not been fully elucidated. This study by ^119^Sn and ^13^C NMR spectroscopy has shown that, on impregnation into Pinus sylvestris sapwood, bis(tributyltin) oxide [(Bu~3~Sn)~2~O] is rapidly converted to tributyltin carboxylates (Bu~3~SnOCO·R) via reaction with components of the wood resin. It is further suggested that the formation of these species is a prerequisite for the known disproportionation reaction which occurs in (Bu~3~Sn)~2~O‐treated timber.
