In line with Scheme 4, pure allyldimethylsilyl triflate (2) was also found to catalyze the addition of 1 to aldehydes with similar ease and efficiency. Due to its very hygroscopic character, this compound is difficult to handle and its in situ preparation from 1 and AgOTf is therefore highly advantageous from the preparative point of view.

Allyldimethylsilyl triflate (2) has been previously used in stoichiometric amounts for the allylation of p-methoxybenzaldehyde which is assumed to proceed via the same cationic 6-membered transition state as shown in Scheme 4, cf.: Brook, M. A.; Crowe, G. D.; Hiemstra, H. Can. J. Chem. 1994, 72, 264.
