Conclusions
-
1.
The IR and Raman spectra of MeCOPMe2, MeCOP(i-C3H7)2, MeCOP(t-C4H9)2, and Me3CCOP(t-C4Hg9)2 in the liquid phase have been studied and interpreted. The normal vibrations of the CC(O)PC2 skeleton have been analyzed.
-
2.
The force constant for the CO bond is significantly lower in the acylphosphines than in acetone.
-
3.
In the liquid phase, the acylphosphines each exist as a single conformer with one plane of symmetry.
