Literature References

Trialkyloxonium salts, also known as Meerwein's salts, are powerful alkylating agents: Chem. Ber., 89, 209, 2060 (1956). For a brief feature on uses of Meerwein's salts in synthesis, see: Synlett, 195 (2004).

In combination with a hindered base, e.g. N-Ethyl­diisopropyl­amine, A11801, is a convenient reagent for the conversion of carboxylic acids to their ethyl esters by O-alkylation: Tetrahedron Lett., 4741 (1971); Org. Synth. Coll., 6, 576 (1988).

Secondary and tertiary amides are O-alkylated to give immonium salts and imino ethers, respectively. Reduction with borohydride provides an effective amide to amine conversion: Tetrahedron Lett., 61 (1968):

Likewise, N-alkylation of nitriles results in their activation to reduction by triethylsilane to give aldehydes, via the imines: Synthesis, 420 (1973); J. Chem. Soc., Chem. Commun., 45 (1974); J. Org. Chem., 46, 602 (1981).
