A series of aroylphosphanes have been prepared in good yield by base-free condensation of the respective aroyl chloride and HPPh2. Alongside the cyclophane m-{-C(O)C6H4(C(O)PMe)}(2) (1), the IR spectroscopic signatures of C6H4R{C(O)PPh2} (R = 3-Me-2, 3-CH2Cl3, 4-CO2Me4, 4-CN5) and the bis(aroylphosphanes) C6H4{2,6-C(O)PPh2}(2) (6) and C6H3N{2,6-C(O)PPh2}(2) (7) are consistent with a manifestation of "phosphomide" character; however, weight of evidence suggests negligible contribution from this canonical form. Comparison is drawn to the structurally characterised O=P(C6H5Me-2)(3) (8) in which the lone pair is sequestered. The coordination of 2-5 to rhodium(I), palladium(II) and platinum(II) is described, affording rare examples of aroylphosphane complexes of the platinum-group metals.
