9. We have also used EtOH, i-PrOH and n-BuOH in this reaction, but yields of corresponding products 8 were low. The weak acidity of these alcohols may be the factor in the reduction of yields.
10. We have also used less reactive aldehydes and ketones in this reaction, but no products were observed even at reflux temperature (toluene as solvent) after 24 h. TLC indicated that the solution contained ylide 5 and the starting aldehyde or ketone.
