Procedure

Dibutyl thiomalate 140 grams (93% assay) was warmed to 90° C and dibutyltin oxide 125 grams was added slowly with stirring and continued heating. The dibutyltin oxide had dissolved by the time the mixture reached 130° C to give dibutyltin mono (dibutyl thiomalate) a viscous liquid.

Workup

  1. temperaturecontinued heating
  2. customreached 130° C
