| Abstract: | Abstract It will be shown that 5-phenyldibenzophosphole is suitably described as a triarylphosphine compound. A study of the corresponding phosphole selenide and triarylphosphine selenide complexes leads to some interesting insight into the nature of the phosphorus-selenium bond. Aspects such as double-bond character, s-character and limiting bond length are discussed on the basis of NMR, IR and X-Ray crystallographic measurements. The relationships found are considered in view of both the steric and electronic properties of the parent phosphine compounds. |
