UNERWARTETE REAKTIONSPRODUKTE VON N-METHYL-N-TRIMETHYLSILYLTRIFLUORACETAMID (MSTFA) MIT ALDEHYDEN

Ende, M.,Luftmann, H.

, p. 5167 - 5170 (2007/10/02)

Aldehydes react with MSTFA (N-methyl-N-trimethylsilyl-trifluoroacetamide) to give E/Z-silylenolethers and surprisingly addition products of the reagent to the carbonyl group.The mass spectra of the MSTFA/aliphatic aldehyde adducts are dominated by a key fragment of m/z 228 formed by elimination of the alkyl part.With MSTFA/aromatic aldehyde adducts this fragmentation is replaced by M-H and M-CH3N.8COCF3 (M-126 amu) ions.
