A practical synthesis of a variety λ5-phosphinines, which show distinct fluorescence both in solution and solid state, is described. Both C4-selective electrophilic substitutions the following conversions realized an easy preparation wide range derivatives having several substituents for electronic modification, provides potential fine-tuning photophysical properties.
