• The reaction can also be carried out to give the primary amine on hydrolysis (Delepine reaction). For conversion of allylic halides to amines, see, e.g.: Org. Synth. Coll., 5, 121 (1973); 9, 666 (1998).
• For a review of applications in organic synthesis, see: Synthesis, 161 (1979).
• Formylation of arylamines and phenols in the presence of acid to give aldehydes (Duff reaction) generally gives low yields: J. Chem. Soc., 547 (1941); Org. Synth. Coll., 4, 866 (1963). In TFA, formylation of aromatic hydrocarbons occurs in good yield with para-selectivity: J. Org. Chem., 37, 3972 (1972). Careful control of reaction conditions enables 4-substituted phenols in TFA to be converted to either 2-formyl or 2,6-diformyl derivatives: Synthesis, 1029 (1998).
• Can be used as a Mannich reagent, e.g. for the ɑ-methylenation of ketones: Synth. Commun., 26, 1775 (1996). For example with reaction scheme, see Propiophenone, A15140.
• Benzylic halides form quaternary salts with hexamine which undergo oxidation during hydrolysis to give aldehydes (Sommelet reaction): Org. React., 8, 197 (1954); Org. Synth. Coll., 3, 811 (1955); 4, 690, 918 (1963). Benzylamines can also be converted to benzaldehydes; see e.g.: Org. Synth. Coll., 5, 668 (1973).
