Synthesis and characterisation of trisarylphosphine selenides: Further insight into the effect of fluoroalkylation on the electronic properties of trisarylphosphines

Variations in the magnitude of the 1JSeP coupling constants for a range of phosphorus(V) selenides allow the efficiency of different spacer groups at insulating the phosphorus centre in triarylphosphines from highly electron-withdrawing perfluoroalkyl groups to be established.

The electronic influence of perfluoroalkyl groups in a range of trisarylphosphines is conveniently assessed using the 1JSeP coupling constant of the trisarylphosphorus(V) selenides.Figure optionsDownload as PowerPoint slide
