Yield:-

Reaction Conditions:

at 250; for 0.5 h;Product distribution / selectivity;Inert atmosphere;

Steps:

1.5
Step (1-5): Alkyl Group Redistribution Reaction; 125.3 g of the mixture obtained in step (1-4) were placed in a 200 mL metal pressure vessel (Model TSV-N2, Taiatsu Techno Corp., Japan) under a nitrogen atmosphere. The metal pressure vessel was immersed in an oil bath heated to 250°C and heated for 30 minutes. After allowing the metal pressure vessel to cool to the vicinity of room temperature, 124.5 g of reaction liquid were recovered. When 1H- and 119Sn-NMR measurement were carried out on the reaction liquid, the reaction liquid was determined to be a mixture containing di-n-butyl diacetoxy tin and n-butyl triacetoxy tin, and the content of di-n-butyl diacetoxy tin in the mixture was 96.3 wt%.
