Summary
-
1.
We have measured the integral intensities of carbonyl absorption in aroylmethylene triphenylphosphoranes and their salts. The observed facts are discussed from the point of view of electron donor and electron acceptorproperties of the phosphorus atom and the aromatic nuclei of the aroyl groups.
-
2.
We have suggested a relationship for the absorption bands in the region 1317–1390 cm−1 for aryl and 1389–1412 cm−1 for aroylmethylene triphenylphosphoranes to oscillation of the P=C bond.
