Tributyltin compounds have been used as fungicides in paper production and preservation, as preservatives for timber, and as insecticides.　The present research was undertaken with the object of preparing tributyltin compounds directly from tin, butyl iodide and zinc dust by one step process. It has been found that, under suitable conditions, tributyltin compound is predominantly produced by the reaction of butyl iodide and zinc dust with dibutyltin diiodide, which is obtained easily by the direct reaction with tin and butyl iodide.　A typical preparation of this compound was carried out as follows: Tinfoll (11.9 g) was dissolved in butyl iodide (44.1 g) in the presence of catalyst (butanol,cellosolve etc. 2.4 g,) and the resulting solution was heated at I45℃, under stirring for 3 hours, until tin was almost disappered. To this solution (containing dibutyltin iodide) zinc dust (8.4 g) and butyl iodide (I8.5 g) were added and then the reaction mixture was heated at I30℃ under stirring for 3 hours.　The working-up of the reaction products gave 23.0g (77 % based on tin) of bistributyltin oxide, 0.5g (2%) of dibutyltin oxide and 1.0g (3%) of tetrabutyltin The total yield of butyltin compounds was 82%.
