Abstract: α-Alkoxynitrile 1 in the presence of tris(methylthio)methyllithium 2 at –78ºC gave the dimer 5 instead of the expected C1-elongated product 3. The formation of compound 5 is explained in terms of anion formation and self-condensation, a variant of the Thorpe reaction. Scrutinizing the 1H NMR spectra revealed that the enamine tautomer 5b is predominant over the imine 5a in the solvents investigated.
Keywords: Thorpe reaction; self-condensation
