Pd(PPh3)4-catalyzed decarbonylation of the phosphaketene Mes* PCO (1, Mes* = 2,4,6-(t-Bu)3C6H2) gives the diphosphene Mes* P=PMes* (2). Related reactions of 1 with zerovalent Pd and Pt phosphine complexes afford diphosphaureylene complexes ML2[Mes*PC(O)-PMes*] (L2 = chelating diphosphine), whose structure and properties depend markedly on the metal and ancillary ligands; Pd(dppf)[Mes*PC(O)PMes*] (12, dppf = 1,1?-bis(diphenylphosphino)ferrocene) also catalyzes the title reaction.

A document type is Patent, introducing its new discovery.

The invention discloses a method for preparing ferrocene diphosphine ligand, and belongs to the field of organic synthesis. The method comprises the following steps: by taking ferrocene as an initial raw material and boron trifluoride diethyl etherate as a catalyst, reacting with diaryl phosphine oxide or dialkyl phosphine oxide, hydrolyzing so as to obtain tertfluoborate of a ferrocene diphosphine compound, and performing heating backflow deprotection in methanol, thereby obtaining the ferrocene diphosphine compound. Compared with the prior art, the method is gentle in reaction condition, simple in aftertreatment, and relatively applicable to industrial production, and the yield is greater than 90%. The prepared ferrocene diphosphine can be used as ligand of a metal catalyst, and can be used in the fields such as organic optoelectronic materials and medicines.

New silver(I) complexes have been synthesised from the reaction of AgNO3, monodentate PR3 (PR3 = P(o-tolyl)3, P(m-tolyl)3, P(p-tolyl)3, P(p-C6H4F), SeP(C6H5)3) or bidentate tertiary (dppe = bis(diphenylphosphane)ethane, dppf = 1,1?-bis(diphenylphosphane)ferrocene) phosphanes and potassium dihydrobis(3-nitro-1,2,4-triazolyl)borate, K[H2B(tzNO2)2]. These compounds have been characterized by elemental analyses, FT-IR, ESI-MS and multinuclear (1H and 31P) NMR spectral data. The adduct {[H2B(tzNO2)2]Ag[P(m-tolyl)3]2} has been characterized by single crystal X-ray studies. In the former, the H2B(tzNO2)2 acts as a monodentate ligand utilizing the coordinating capability of only one of the additional (exo-) ring nitrogens to complete the coordination array about the silver atom.

The reactions of the zerovalent palladium complex [Pd2(dba)3]·CHCl3 (dba = dibenzylideneacetone, PhCH=CH-C(O)-CH= CHPh), in the presence of bidentate phosphorus ligand L2 and dioxygen, with esters of 3-oxopentanedioic acid (RCH2COCH2R) in diethylether, afford, in good yield, the palladocyclobutan-3-one compounds [Pd(CHRCOCHR)L2] [R = CO2Me, L2 = dppe, dppp, dppb, dppf]. The compounds [Pd(CHRCOCHR)L2] [R = CO2Me, L2 = dppe, dppp, dppb, dppf; R = CO2Et, L2 = dppe] are also formed by treating dichloromethane solution of [Pd(COD)Cl2] (COD = cyclo-octa-1,5-diene) with RCH2COCH2R in the presence of silver(I) oxide and the appropriate bidentate ligand. Ligand exchange reactions of [Pd(eta3-CHRCOCHR)(L?)2], (R = CO2Me, L? = PPh3 or AsPh3) complexes with appropriate chelating phosphorus donor ligand in dichloromethane have also afforded new complexes [Pd(CHRCOCHR)L2] (L? = PPh3, L2 = dppe, dppp; L? = AsPh3, L2 = dppe, dppp, dppb, dppf). Spectroscopic data (IR, NMR, FAB MS) for the new compounds are reported.

The crystal and molecular structure of anhydrous 1,1′-bis(diphenylphosphino)ferrocene sulphide, Fe[C5H4P(S)Ph2]2 (dppfS2), is reported and compared with the hydrated oxide analogue, Fe[C5H4P(O)Ph2]2*2H2O (dppfO2*2H2O). It consits of two phosphoryl cyclopentadienyl rings [P-S =1.938(2) A] sandwiching an Fe(II) centre. With four molecules per cell, the molecule is crystallographically required to sit on an inversion centre andhence the two rings are staggered. The thermal properties of [Fe(C5H4PP h2)2] (dppf), dppfO2*2H2O and dppfS2 were studied together with Fe(Cp)2 and Ph3PO*H2O by TGA and DSC. The thermal stability decreases in the order dppfO2>dppf>dppfS2. The hydrogen-bonded hydrate in dppfO2*2H2O is removed upon heating to 110-160°C.

N,N-Diethyl-N?-4-nitrobenzoylselenourea (HLSe) reacts with the mono- and dinuclear phosphine gold(I) chloro complexes [AuCl(PR 3)] (R=Ph, o-tol, Et) and [Au2Cl2(mu-P-P)] (P-P=dppm, dppe, dppp, dppb, dppf) in the presence of base to give gold(I) phosphine selenoureato complexes [Au(LSe)(PR3)] [R=Ph (1), o-tol (2), Et (3)], [Au2(LSe)2(mu-P-P)] [P-P=dppm (4), dppe (5), dppp (6), dppb (7), dppf (8)] in excellent yields. The compounds were fully characterised by spectroscopic methods and, in the case of compounds 1, 5 and 8, by single crystal X-ray diffraction. The compounds consist of a gold atom bound in linear fashion to the phosphine ligand and the selenium atom from the deprotonated acylselenourea. These complexes thus represent the first examples of acylselenoureato metal compounds in which the ligands do not adopt the typical O,Se chelating mode but rather coordinate to the metal only through the selenium atom.
