Ma. Delasheras et al., SYNTHESIS OF ALDEHYDES FROM ACYL CHLORIDES VIA 1-(ACYLMETHYLAMINO)-3-METHYLIMIDAZOLIUM SALTS, Tetrahedron letters, 36(3), 1995, pp. 455-458
The reaction of acyl chlorides with 1-amino-3-methylimidazolium salts,
followed by N-methylation of the resulting H-aminides, afforded 1-(ac
ylmethylamino)-3-methylimidazolium salts which, upon treatment with DI
BALHgave aldehydes in good yields. A nalogously, dialdehydes were obta
ined from the corresponding bis-salts.
