1.The spectral characteristics of H complexes with compounds of tervalent phosphorus are distorted substantially in presence of very small amounts of the corresponding derivatives of quinquevalent phosphorus (0.2-0.5percent) as impurity. 2.The method of checking the purity of compounds of tervalent phosphorus by the absence of the absorption band of the phosphoryl group is less effective than checking by the band of the H complexes with the samples investigated.

Mono- and bis-(trialkyl- and triaryl-phosphine)copper(i) derivatives containing anionic bis-, tris- and tetrakis(pyrazol-l-yl)borates were prepared from CuCl, [CuBr(Me2S)] or [Cu(C6H6)0.5(O3SCF3)]2, R3P (R = phenyl, benzyl, cyclohexyl, o-, m-, or/7-tolyl) or R’Ph2P (R’ = methyl or ethyl), and M[HB(pz)4_] (M = Na or K, n = 0, l or 2; Hpz = pyrazole in general; in detail, pyrazole (Hpz), 3,5-dimethylpyrazole (Hm2pz), 3-methylpyrazole (Hmpz)) and characterized through analytical and spectral measurements (IR, ‘H and 3IP NMR). The same complexes can be obtained also from the reaction of [Cu(O2NO)(PR3)J with M[HB(pz)4.]. These air-stable compounds are non-electrolytes in CH2C12 and in acetone, in which they slowly decompose even with the strict exclusion of oxygen. Low-temperature single crystal structural characterizations were undertaken for several of them. The structurally authenticated arrays fall into three different types: (a) [Cu((pz)2BH(pz)2_)(PR3)2] with a four-co-ordinate P2Cu(N2) co-ordination sphere, (b) [Cu((pz)3BH)(PR3)] with a four-co-ordinate PCu(N3) co-ordination sphere, (c) [Cu((pz)2BH(pz)2.)(PR3)] with a three-co-ordinate PCu(N2) co-ordination sphere.

An NCN pincer palladium complex was developed as a probe molecule to index the coordination ability of various monodentate ligands. Coordination constants of 27 monodentate ligands (L) with a pincer palladium complex to form complexes of the type ArPd(L)2Cl were determined by 1H NMR spectroscopy. This allowed the coordination ability of a wide variety of ligands, including P-coordinating ligands (phosphane, phosphite), as well as As-coordinating AsPh3, and N-coordinating pyridine, to be indexed. The differential between the highest/lowest coordination constants was 10 12. The relative coordination ability is described in a logarithmic manner, log(Keq(L)/Keq(PPh3)), with respect to the value of PPh3 to exhibit high linearity in the Hammett plot.

The reactivity of the tetranuclear metallated palladium compound {Pd[mu2-(C6H4) PPh2]Br}4 (1) with different ligands has been investigated with the aim of evaluating the influence of the entering ligand on the nature of the reaction products. The results confirmed the ability of the ligand [(C6H4)PPh2]- to expand a bridging [mu2-] or a chelating [eta2-] coordination mode, depending on the auxiliary ligands present in the complex. Bulky phosphines stabilize mononuclear species of formula {Pd[eta2-(C6H4)PPh2]Br[P]}, with a four-atom metallocycle, while small phosphines dinuclear compounds. The molecular structures of three different metalated palladium compounds have been give determined by single-crystal X-ray crystallography; the tetranuclear {Pd[mu2-(C6H4) PPh2]Cl)4 (2), the dinuclear-{Pd[mu2-(C6H4) PPh2]Br [PMe3]}2 (3), and the mononuclear {Pd[eta2-(C6H4)PPh2]Br[PCBr]}, (PCBr = P(o-BrC6H4)-Ph2) (9) were obtained, the first one by halogen exchange reaction and the others by frame degradation of 1.

The reaction of (PPh3)4CuClO4, (PPh3)2CuCl, (Cy3P)2CuNO3 and (Cy3P)2CuClO4 with an excess of monodentate heterocyclic N-donor ligand (QH in general, in detail: ImH = imidazole, 1-MeimH = 1-methylimidazole, 2-MeimH = 2-methylimidazole, 4-PhimH = 4-phenylimidazole, BimH = benzimidazole, 1-BzimH= 1-benzylimidazole, pzH = pyrazole, pz?H = 3,5-dimethylpyrazole) in diethyl ether or benzene resulted in the formation of new 2:2:1 [(PPh3)2(QH)2Cu]ClO4 (QH = ImH, 1-MeimH, 2-MeimH, 4-PhimH, BimH, pzH) and [(PCy3)2(QH)2Cu]NO3 (QH = 4-PhimH, BimH), 1:3:1 [(PPh3)(1-BzimH)3Cu]ClO4, [(PCy3)(I-MeimH)3Cu]ClO4 and [(PCy3)(QH)3Cu]NO3 (QH = ImH, 1-MeimH, pzH), 2:1:1 [(PPh3)2(QH)CuCl] (QH = ImH, 2-MeimH, 4-PhimH, BimH, 1-BzimH), [(PCy3)2(QH)Cu]NO3 (QH= 1-BzimH, pz?H) and [(PCy3)2(QH)Cu]ClO4 (QH = 2-MeimH, 4-PhimH, BimH, 1-BzimH, pzH, pz?H), 1:2:1 [(PCy3) (2-MeimH)2Cu]NO3 and [(PCy3)(ImH)2Cu]ClO4 and 1:1:1 [(PPh3)(1-MeimH)CuCl] adducts. With the bidentate donors bis(pyrazol-1-yl)methane (L1), bis(3,5-dimethylpyrazol-l-yl)methane (L2) and bis(4-methylpyrazol-l-yl)methane (L4), 2:1:1 [ (PPh3)2(L) Cu]ClO4 and 1:1:1 [(PCy3)(L)Cu]ClO4 complexes were obtained, whereas the exopolydentate bis(1,2,4-triazol-1-yl) methane (L3) in similar conditions yielded 1:1:1 [(PPh3)(L3)Cu]ClO4 and [(PCy3)(L3)Cu]NO3, and 1:2:1 [(PCy3)(L3)2Cu]ClO4 derivatives. Breaking of the bridging C(sp3)-N bond in the bidentate bis (pyrazol-1-yl) methane occurred when the reaction between L1 and (PCy3)2CuNO3 was carried out in diethyl ether under aerobic conditions, the derivative [ (PCy3) (pzH)3Cu]NO3 being formed. In methanol in the presence of base, ImH, 2-MeimH, 4-PhimH and BimH react with (PPh3)2CuCl giving the sparingly soluble complexes [(PPh3)2(Im)Cu] · 1/2H2O, [(PPh3)2(2-Meim)Cu] · H2O, [(PPh3)(4-PhJm)Cu] and [ (PPh3) (Bim)Cu], respectively. Reaction of [(PPh3)2(ImH)2Cu]ClO4 with PCy3, PBz3 (Bz = benzyl), P(p-tolyl)3 and (Ph2PCH2)2 (abbreviated Diphos) resulted in the formation of compounds [(PPh3)(PCy3)(ImH)2Cu]ClO4, [(PPh3)(PBz3)(ImH)Cu]ClO4, [(PPh3)P(p-tolyl)3(ImH)2Cu]ClO4 and [(Diphos)2Cu]ClO4, respectively, whereas reaction with 1,10-phenanthroline (Phen) and 2,2?-bipyridyl (Bipy) produced [ (PPh3)2(ImH) (Phen)Cu]ClO4 and [(PPh3)2(ImH) (Bipy)Cu]ClO4, respectively. While PCy3, PBz3 and P(p-tolyl)3 were not able to displace the triphenylphosphine from [(PPh3)2(L1)Cu]ClO4, Phen and Bipy in the same conditions formed the derivatives [ (PPh3)2(Phen)Cu]ClO4 and [ (PPh3)2(Bipy)Cu]ClO4. All of the complexes were characterized by IR and far-IR data, conductivity, 1H NMR and in some cases also with UV, 13C and 31P NMR and molecular weight measurements. The structure of [ (Cy3P)2(pzH)Cu]ClO4 · CH3OH was determined by single crystal X-ray diffraction: monoclinic, space group Pn, Z=2, a=9.949(7), b=13.128(4), c=16.588(8) A, beta=91.15(7). The copper atom exhibited a distorted ideal trigonal planar geometry involving two phosphine groups (Cu-P: 2.262(9) and 2.272(6) A;P-Cu-P: 132.3(7)) and one pyrazole ligand (Cu-N: 2.047(18) A) coordinating through a pyridine-like nitrogen atom. The pyrazole donor of one molecule was hydrogen bonded to a molecule of methanol, which in turn was hydrogen bonded to the ionic perchlorato group.

The distinct reactivity of 1,6-enynes in the presence of a trinuclear metal complex activated by a carboxylic acid is presented. The triplatinum catalyst enables the cyclization of the substrate and subsequent incorporation of a nucleophile in the final product. In contrast, sequential cyclization/double bond shift occurs under analogous conditions in the presence of the corresponding tripalladium complex.
