  • For use with Dimethoxymethane, A12055, in the protection of alcohols as their methoxymethyl (MOM) ethers, avoiding the carcinogenic chloromethyl methyl ether, see: Synthesis, 276 (1975); Org. Synth. Coll., 9, 539 (1998).
  • One of the most efficient drying agents which is used in various dehydrations and related reactions.
  • Several lower viscosity alternatives to the useful dehydration and cyclization agent polyphosphoric acid (PPA) can be prepared from phosphorus pentoxide:
  • Reaction with ether in chloroform gives polyphosphoric ester, PPE: Biochem. Biophys. Acta., 80, 1 (1964). The chloroform solution is mobile and useful for dehydrations such as: The Bischler-Napieralski reaction (see 2-Phenylethylamine, A13402), and related reactions: Tetrahedron Lett., 2419 (1964); the Fischer indole synthesis (see Phenylhydrazine, A11246): Chem. Ind. (London), 473 (1965); the direct, high-yield formation of thiocarboxylic esters by reaction between the carboxylic acid and the thiol: Synthesis, 134 (1982).
