A series of different crosslinked styrene-divinylbenzene-copolymers bearing diphenyl phosphinomethyl groups was reacted with methyl iodide in ethanol.The quaternization has been controlled by elementary analysis of P and I and by ir spectroscopy using a key band at 1123/cm.The spectroscopic method gave satisfactory results with sample amounts of 5 mg polymer in KBr discs.In resins containing up to 7 percent divinylbenzene the methylation was almost quantitative within 1 h refluxing.However, in highly crosslinked polymers (>10percent DVB) containing residues of free chloromethyl groups and intraresin quaternized phosphino groups we observed side reactions in boiling ethanol.These could be avoided by performing the methylation in toluene at room temperature.

A new type of phosphonium phase-transfer catalyst prepared from easily available chiral amino acids was evaluated in a model reaction between oxindole and methyl vinyl ketone, and the catalyst derived from isoleucine was found to be the best. Michael additions of 3-monosubstituted oxindoles to methyl vinyl ketone, acrolein or propargyl aldehyde proceeded smoothly to afford 3,3-disubstituted oxindoles in good to excellent yields with moderate to excellent ees.

Depending on the conditions used, reactions of benzyldiphenylphosphine (HL1) with Na2PdCl4 on silica gel or with Pd(OAc)2 on the same absorbent followed by treatment with LiCl provide one or more of the four compounds: the cyclopalladated binuclear complex [(mu-Cl)PdL1]2 (1), cis and trans isomers of the coordination complex PdCl2(HL1)2 (3), the binuclear coordination complex [(mu-Cl)PdCl(HL1)]2 (4), and compound PdCl2(HL1)3 (5). The 56% yield of complex 1 achieved using the reaction with Na2PdCl4 and NaOAc on SiO2 is higher than that reported for the direct cyclopalladation of PBnPh2 with Pd(OAc)2 in AcOH. X-ray diffraction studies of the cyclopalladated dimer 1 and the coordination complex cis-3 are reported.

The pre-chelate molecules 2-(diphenylphosphanyl)-N,N-dimethylaniline, [2-(diphenylphosphanyl)benzyl]dimethylamine, 1-(diphenylphosphanyl)-2-ethylbenzene, 1-(diphenylphosphanyl)-2-isopropylbenzene, and 2-(diphenylphosphanyl)benzonitrile, in a reaction with [CoMe(PMe3)4], eliminate methane to afford the selectively 6-ortho-metalated complexes 1-5 that contain four-membered metallacycles. The molecular structure of 3 shows a tbp-coordinated cobalt atom, with axial C and PMe3 donor groups. Metalation in the aliphatic side-chain occurs with 2-(diphenylphosphanyl)toluene, giving complex 6 that contains a five-membered metallacycle. Benzyldiphenylphosphane is selectively orthometalated in the benzyl group, affording 7. As shown by the molecular structures, complex 7 is a true ligand isomer of 6. Substitution of a trimethylphosphane group in compounds 4 and 6 by ethene gives the pentacoordinate complexes 8 and 9, respectively. The ethene ligand is pi-coordinated in the equatorial plane of a trigonal bipyramid. Under 1 bar of CO, complex 6 forms monocarbonyl complex 10. Carbonylation of complexes 3 and 4 proceeds by insertion of CO into the Co-C bond under ring expansion, affording the aroylcobalt complexes 11 and 12, respectively. Complex 6 reacts with iodomethane in an oxidative substitution reaction yielding a structurally characterized octahedral complex mer-13, which eliminates a methyl group in THF at 20 C to form a pentacoordinate cobalt(II) complex 14. Complex 3 oxidatively adds iodomethane in a stereoselective cis addition to give the cobalt(III) complex mer-15, which retains its four-membered metallacycle and the CoCH3 group.

Sequential treatment of IrCl3· nH2O with 2 equiv of benzyl diphenylphosphine (bdpH) and then 1 equiv of 3-trifluoromethyl-5-(2-pyridyl) pyrazole (fppzH) in 2-methoxyethanol gave formation to three isomeric complexes with formula [lr(bdp)(fppz)(bdpH)H] (1-3). Their molecular structures were established by single crystal X-ray diffraction studies, showing existence of one monodentate phosphine bdpH, one terminal hydride, a cyclometalated bdp chelate, and a fppz chelate. Variation of the metal-ligand bond distances showed good agreement with those predicted by the trans effect. Raman spectroscopic analyses and the corresponding photophysical data are also recorded and compared. Among all isomers complex 1 showed the worst emission efficiency, while complexes 2 and 3 exhibited the greatest luminescent efficiency In solid state and in degassed CH2Cl 2 solution at room temperature, respectively. This structural relationship could be due to the simultaneously weakened hydride and the monodentate bdpH bonding that are destabilized by the trans-pyrazolate anion and cyclometalated benzyl group, respectively.

As the first example of the alpha-phosphine-substituted thioacylamides, N-methyl 2-(diphenylphosphino)-2-phenylthioacetamide (1b) was synthesized by nucleophilic addition of the carbanion of benzyldiphenylphosphine to methylisothiocyanate.The phosphine sulfide 3b is obtained by sulfuration of 1b.The corresponding P=O derivatives 2b-d were prepared in analogy to 1b from the phosphine oxides Ph2P(O)R (R=CH2C6H5 (b), CH2CN (c), C2H5 (d)).Phosphorus-substituted (thio)acetamides were obtained by metathesis of lithium diphenylphosphide or methyl diphenylphosphinite with N-methyl chloro(thio)acetamide: Ph2PCH2C(O)NHMe (4a), Ph2P(O)CH2C(X)NHMe (X=O: 5a, X=S: 2a).The phosphinothioacetamide Ph2PCH2C(S)NHMe (1a) is not accessible by this route.

Ambiphilic molecules, which contain a Lewis base and Lewis acid, are of great interest based on their unique ability to activate small molecules. Phosphine boronates are one class of these substrates that have interesting catalytic activity. Direct access to these phosphine boronates is described through the iridium-catalyzed C?H borylation of phosphines. An unconventional cationic iridium catalyst was identified as optimal for a range of phosphines, providing good yields and selectivity across a diverse class of phosphine boronates (isolated as the borane-protected phosphine). A complimentary catalyst system (quinoline-based silane ligand with [(COD)IrOMe]2) was optimal for biphenyl-based phosphines. Selective polyborylation was also shown providing bis- and tris-borylated phosphines. Deprotection of the phosphine boronate provided free ambiphilic phosphine boronates, which do not have detectable interactions between the phosphorus and boron atoms in solution or the solid state.
