- Addition of 2 moles of butyllithium to trimethylsilyl acetic acid gave none of desired product
- (CH3)3SiCH2CO2H Presumably, enolization competes effectively with addition

- Perchloric acid in CCl4 was used for the elimination of trimethylsilanol
- For hindered ketones such as 2 we observed ca. 20% enolization. Hence, the yield given represents an additional recycling of the initial reaction product
