Conditions

Temperature: 50 °C

Procedure

Sodium caprylate 6.6 g was added to 200 ml of isopropanol, and with stirring, the mixture was heated to 50° C. To the resulting solution was added 22.2 g of tris(β,β-dimethylphenethyl)tin chloride over 30 minutes. The mixture was further stirred for 30 minutes. The insoluble material precipitated was separated by filtration, and the filtrate was concentrated to give 25.1% (yield 94.8%) of tris(β,β-dimethylphenethyl)tin caprylate as a slightly pale yellow viscous syrup.
