9. In this reaction, TBAF may act partially as a source of proton since GLC analysis of the reaction mixture showed the presence of tri-n-butylamine resulting from the Hofmann degradation of TBAF.
10. For example, the reaction of 6a with hydrocinnamaldehyde gave 7a (43%) only and no hydroxymethylation product could be detected.
