Highly Selective Phosphinylphosphination of Alkenes with Tetraphenyldiphosphine Monoxide
Sato, Yuki,Kawaguchi, Shin-Ichi,Nomoto, Akihiro,Ogawa, Akiya
, p. 9700 - 9703 (2016)
In sharp contrast to tetraphenyldiphosphine, which does not add to carbon–carbon double bonds efficiently, its monoxide, [Ph2P(O)PPh2] can engage in a radical addition to various alkenes, thus affording the corresponding 1-phosphinyl-2-phosphinoalkanes regioselectively, and they can be converted into their sulfides by treatment with elemental sulfur. The phosphinylphosphination proceeds by the homolytic cleavage of the PV(O)?PIIIsingle bond of Ph2P(O)PPh2, followed by selective attack of the phosphinyl radical at the terminal position of the alkenes, and selective trapping of the resulting carbon radical by the phosphino group. Furthermore, the phosphinylphosphination product could be converted directly into its platinum complex with a hemilabile P,O chelation.

Indium(III) promoted oxidative P-P coupling of silylphosphines
Cartlidge, Ashleigh J.,Matthews, Peter D.
, (2022/01/28)
The reaction of indium(III) salts with Ph2PSiMe3 and PhP(SiMe3)2 gives rise to a one- and two-electron reductive P-P coupling respectively, with the formation of new P-P bonds resulting in the preparation of (Ph2P)2 and the cyclicoligophosphane compounds (PhP)4 and (PhP)6.

Berthold, Chantsalmaa,Thomas-Hargreaves, Lewis R.,Ivlev, Sergei I.,Buchner, Magnus R.
, p. 651 - 658 (2021/10/12)
The diphenylphosphinites [(THF)Li(OPPh2)]4 and [(THF)2Be(OPPh2)2] have been synthesized via direct deprotonation of diphenylphosphine oxide with n BuLi and BePh2, respectively, as well as via salt metathesis. These compounds were characterized by multinuc
Photoinduced Coupling Reaction of Diphenyl(2,4,6-trimethylbenzoyl)phosphine Oxide with Interelement Compounds: Application to the Synthesis of Thio- or Selenophosphinates
Sato, Yuki,Kawaguchi, Shin-Ichi,Nomoto, Akihiro,Ogawa, Akiya
, p. 3558 - 3567 (2017/08/16)
Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TMDPO) is a radical initiator widely used in the field of macromolecular chemistry, but not often applied in synthetic organic chemistry. We have focused on the use of TMDPO as a phosphorus source in reactions with different E - E compounds, where E - E represents a heteroatom-heteroatom bond, under photoirradiation. Interestingly, the cross-coupling reaction between TMDPO and disulfides or diselenides successfully affords thio- or selenophosphinates and thio- or selenoesters, respectively. The synthesis of series of thio- and selenophosphinates by this photoinduced cross-coupling reaction is demonstrated.

PROBLEM TO BE SOLVED: To provide methods of producing a perfluoroalkylphosphine compound improved in a phosphorus element yield and a chemical yield. SOLUTION: A method of producing a perfluoroalkylphosphine compound comprises either reacting a perfluoroalkyl iodide with, e.g., 2,4,6-trimethylbenzoyldiphenylphosphine oxide (TMDPO) or a triarylphosphine such as triphenylphosphine, which are easily available, in the presence of a radical generator such as azobis(isobutyronitrile) or light irradiation, or reacting TMDPO or the like with perfluoroalkyl iodide in the presence of diphenylphosphine, diethylphosphine, dicyclohexylphosphine or the like.

Mixed anhydride complexes of rhodium(i) and ruthenium(ii)-their synthesis and ligand rearrangements
Coetzee, Jacorien,Eastham, Graham R.,Slawin, Alexandra M. Z.,Cole-Hamilton, David J.
, p. 3479 - 3491 (2014/03/21)
The coordination chemistry and solution behaviour of Rh(i) and Ru(ii) complexes derived from mixed anhydride ligands of carboxylic acids and phosphorus acids were explored. Similar to the free ligand systems, mixed anhydride complexes rearranged in solution via a number of pathways, with the pathway of choice dependent on the mixed anhydride employed, the auxiliary ligands present as well as the nature of the metal centre. Plausible mechanisms for some of the routes of rearrangement and by-product formation are proposed. Where stability allowed, new complexes were fully characterised, including solid state structures for four of the unrearranged mixed anhydride complexes and two of the interesting rearrangement products.
Phosphane ligands with enaminoketone scaffold and their palladium complexes
Schmidt, Michael,Heck, Juergen
experimental part, p. 1151 - 1158 (2012/07/28)
The reaction of (Z)-4-aminopent-3-en-2-one with different chlorodiorganylphosphanes established three new ligands composed of a hard and soft coordination site. The soft phosphane site is easily coordinated to palladium(II) as a first step in the potential formation of heterodinuclear complexes. Surprisingly, the formed square-planar dichloridopalladium(II) complexes exhibit exclusively trans configuration. A cis configurated palladium(II) complex can be formed, when the linker between the phosphane and the enaminoketone unit is enlarged and allows more flexibility. The reaction between (Z)-4-(2'-hydroxyethylamino)pent-3-en-2-one and chlorodiorganylphosphanes revealed two new ligands that coordinate to palladium(II). With phenyl substituents at the phosphorus atom a cis palladium complex was obtained, whereas for isopropyl substituents a trans complex was formed. Molecular structures of all complexes were analyzed by single-crystal X-ray diffraction.
