Editing Phosphorine (section)

==History==
The first phosphorine to be isolated is 2,4,6-triphenylphosphorine. It was synthesized by Gottfried Märkl in 1966 by condensation of the corresponding [[pyrylium salt]] and [[phosphine]] or its equivalent ( P(CH<sub>2</sub>OH)<sub>3</sub> and P(SiMe<sub>3</sub>)<sub>3</sub>).<ref name=":0">''G.

The (unsubstituted) parent phosphorine was reported by Arthur J. Ashe III in 1971 by the reaction of 1,4-dihydro-1,1 dibutylstannabenzene and [[phosphorus tribromide]].<ref name="Ashe">{{ cite journal | last1 = Ashe | first1 = A.
