adopting the preparation method of the paradimethylaminobenzaldehyde, the paradimethylaminobenzaldehyde is synthetized by urotropin and N,N-dimethylaniline; mixed acid of trifluoroacetic acid and glacial acetic acid is taken as a catalyst in reaction, so as to synthetize the paradimethylaminobenzaldehyde....
The barrier to rotation around the bond between the formyl group and the complexed ring in para-dimethylamino-π-(tricarbonylchromium) benzaldehyde (I) was determined by 13C NMR spectroscopy at variable temperature and complete line shape analysis. The Δ G ≠ value for the interconversion in I ...
