  • In aqueous DMF, tosylate esters undergo formolysis to formate esters: Synth. Commun., 26, 1031 (1996).
  • Vilsmeier conditions also promote dehydrations, e.g. in cyclodehydration of hydroxyphenols to give cyclic ethers, as an efficient alternative to the Mitsunobu reaction: J. Chem. Soc., Perkin 1, 2249 (1996); J. Org. Chem., 59, 4346 (1994):

R. Giles, CRC Press, Boca Raton, FL (1994). Formylation can be extended to less active substrates, e.g. acenaphthene or mesitylene, with the DMF-triflic anhydride reagent: J. Chem. Soc., Chem. Commun., 1571 (1990). Under Vilsmeier conditions, electron-rich alkenes can be converted to ɑß-unsaturated aldehydes; see, e.g.: Synthesis, 752 (1976); and ketones to ß-chloroenals: Synthesis, 496 (1985); Org. Synth.
