A study on the Kabachnik–Fields reaction of benzaldehyde,propylamine, and diethyl phosphite by in situ Fourier transform IR spectroscopy

The phospha‐Mannich condensation of benzaldehyde, n‐propylamine, and diethyl phosphite carried out at 80°C in acetonitrile takes place via the imine (PhCN Pr) intermediate as suggested by in situ FT‐IR spectroscopy. © 2011 Wiley Periodicals, Inc.
