Acid-catalyzed reaction with alcohols gives 1-ethoxyethyl (EE) ethers, useful as protected derivatives, e.g. in reactions with organometallics. Possible catalysts include: tosic acid: J. Am. Chem. Soc., 101, 7104 (1979); Org. Synth., 76, 199 (1998), PPTS: Tetrahedron Lett., 28, 4303 (1987), or dichloroacetic acid: J. Org. Chem., 37, 1947 (1972). Cleavage of this mixed acetal occurs in dilute acid, more readily than THP ether (see 3,4-Dihydro-2H-pyran, L02731). Protection of cyanohydrins allows use as acyl anion equivalents: Org. Synth. Coll., 7, 381 (1990):

Also used in the protection of phenols as EE ethers which can be cleaved by acid-catalyzed methanolysis: J. Am. Chem. Soc., 119, 8071 (1997).

In the presence of Montmorillonite K10, an addition reaction with diethyl acetals gives the ß-ethoxy acetal of the bis-homologated aldehyde, providing, on acid cleavage, an effective route to the corresponding ɑß-unsaturated aldehyde: Synthesis, 137 (1981).
