Detailed 31P{1H} NMR spectroscopic investigations provide deeper insight into the complex, multi-step mechanisms involved in the recently reported photocatalytic arylation of white phosphorus (P4). Specifically, these studies have identified a number of previously unrecognized side products, which arise from an unexpected non-innocent behavior of the commonly employed terminal reductant Et3N. The different rate of formation of these products explains discrepancies in the performance of the two most effective catalysts, [Ir(dtbbpy)(ppy)2][PF6] (dtbbpy=4,4′-di-tert-butyl-2,2′-bipyridine) and 3DPAFIPN. Inspired by the observation of PH3 as a minor intermediate, we have developed the first catalytic procedure for the arylation of this key industrial compound. Similar to P4 arylation, this method affords valuable triarylphosphines or tetraarylphosphonium salts depending on the steric profile of the aryl substituents.

A number of novel tetra-arylfluorophosphoranes have been synthesised.The most stable form of these compounds is the ionic form PR4+F- (R=aryl) although various other forms have been shown to exist including a molecular monomer PR4F and a dimer PR4+PR4F2-.The i.r. spectra of the ionic forms reveal strong P+...F- interactions.The fluorides are prepared via the hydrogendifluorides PR4+HF2- which contain distorted HF2- ions.
