• Formylating agent: useful replacement for HCN in the Gattermann reaction for the synthesis of aromatic aldehydes: J. Am. Chem. Soc., 76, 290 (1954); Angew. Chem. Int. Ed., 6, 940 (1969); Arch. Pharm., 302, 828 (1969); 304, 362 (1971); with reactive substrates, formylation can be accomplished without a catalyst.
• Also reacts with nucleophiles, e.g. amines, which has been utilized in a quinazoline synthesis: J. Chem. Soc. (C), 1282 (1969):
