✦ Synopsis

The Raman spectra of POCI,, HCONMe,, PhCONMe, and reaction mixtures of POCl, and HCONMe,, and POCl, and PhCONMe, have been recorded in an attempt to establish the nature of the reaction products. Assignments for most of the bands observed in the spectra of the reaction product are given. The spectra were compared with the spectra of the products of the reaction between HCONMe, and SOCI,. Several arguments could be advanced which indicated that the o ~l y product (RP,) formed in the reaction of P0Cl3 with HCONMe, was HCOPOC12NMe2 CI-rather than HCCINMe, OPOCI;. The observed accidental degeneracy of the amide I band at 1668 cm-' in RP, and the imine band at 1665 cm-' in HCCINMe, CI-showed that the usefulness of the amide I and imine bands as characteristic bands is restricted.
