Fluorinated organophosphorus(V) compounds are a very versatile class of compounds, but the synthetic methods available to make them bear the disadvantages of 1) occasional handling of toxic or pyrophoric PIII starting materials and 2) a dependence on hazardous fluorinating reagents such as XeF2. Herein, we present a simple solution and introduce a deoxygenative fluorination (DOF) approach that utilizes

The preparations and spectroscopic characterisation of the hydrolytically unstable As(III) complexes, [AsF3(OPR3)2] (R = Me or Ph) and [AsF3Me2P(O)CH2P(O)Me2}] are described and represent the first examples of complexes of AsF3 with neutral ligands. The crystal structure of [AsF3Me2P(O)CH2P(O)Me2}] contains dimers with bridging diphosphine dioxide, but there are also long contacts between the dimers

2′-bipyridyl produce the insoluble [MoOF4(bipy)], which is probably 7-coordinate. Ph3AsO is quantitatively converted to Ph3AsF2 by [MoOF4(MeCN)], and soft ligands, including Me2S, Me3P and Me3As, reduce the oxide fluoride on contact. Unstable [MoO2F2(MeCN)2] has also been prepared and the X-ray structure of [MoO2F2(MeCN)2]·MeCN is reported. X-ray crystal structures are reported for [MoOF4(Ph3PO)], [MoO2F2(Ph3PO)2]

Evidence for an ionic mechanism involving ‘onium’ monohalide ions is given for halogenations with these reagents when carried out under “Friedel-Craft” conditions although no stable salts containing these ions have as yet been isolated because of intramolecular halogenation. These ions act as sources of positive fluorine. The use of ring deactivated reagents to achieve halogenation is discussed.
