実験手順

Example 8 was repeated using the same reactor and catalyst/support charge. CF3CF2CF2OCF(CF3)CO2SiMe3 (16.20 g, 40.3 mmol) was added dropwise over 1.5 hr. There was obtained 13.94 g of liquid product consisting of an equimolar mixture of PPVE and TMSF. Less than 0.2% starting TMS ester remained, and less than 1% C3F7OCHFCF3 was produced.
