Electrospray mass spectrometric study of homogeneous catalytic system Pd(CF3COO)2-Ph2P(CH2)3PPh2-MeOH/Me2CO-H2O for copolymerization of ethylene and carbon monoxide

AbstractThe catalytic system Pd(CF3COO)2-Ph2P(CH2)3PPh2-MeOH/Me2CO was studied by electrospray mass spectrometry. The {[Pd(dPPP)2]2+ [(dppp)2Pd(CF3COO)]+, [(dppp)Pd(CF3COO)]+, and [(dppp)Pd(CF3COO)2Pd(dppp)]2+} cations were found in the system.

Structural and thermal characterization of galactomannans from non-conventional sources

Galactomannans of Gleditsia triacanthos, Caesalpinia pulcherrima and Adenanthera pavonina were structurally and thermally characterized. Methylation analyses confirmed that these three galactomannans are composed by a 4-linked mannose polymer with galactose side chains attached at the C6 position.

The arylation of [Pt2(μ-S)2(PPh3)4]

The platinum(II) sulfido complex [Pt2(?-S)2(PPh3)4] reacts with potent arylating agents (diphenyliodonium salts, 1-chloro-2,4-dinitrobenzene and 1,5-difluoro-2,4-dinitrobenzene) to produce mono-arylthiolate complexes [Pt2(?-S)(?-Saryl)(PPh3)4]+. The phenylthiolate complex [Pt2(?-S)(?

Reactivity of pyrrole pigments, XIX. On the structure of Cu(II) and Zn(II) chelates of dipyrrins in solution

SummaryThe Cu(II) and Zn(II) chelates of 1,2,3,7,9-pentamethyldipyrrin and 1,2,3,7,9-pentamethyl-8-sulfodipyrrin are studied. When metal acetates are used for the formation of the metal complexes, dipyrrinate metal acetates could be detected as precursors of thebis-dipyrrinates.

Transfer of Man9GlcNAc to

In this paper, we found that the endo-A can also transfer an oligosaccharide, Man9GlcNAc, tol-Fuc using Man9GlcNAc2Asn as donor substrate in a medium containing 35% acetone. The transglycosylation yield was greater than 25% when 0.2m l-Fuc was used as acceptor.

Thallium(III) complexes of the metalloligands [Pt2(μ-S)2(PPh3)4] and [Pt2(μ-Se)2(PPh3)4]

Reactions of [Pt2(?-S)2(PPh3)4] with the organothallium(III) halide compounds Ar2TlBr (Ar=Ph and p-ClC6H4) and PhTlBr2 gave organothallium(III) adducts [Pt2(?-S)2(PPh3)4TlAr2]+ and [Pt2(?-S)2(PPh3)4TlBrPh]+; the corresponding selenide complex [Pt2(?-Se)2(PPh3)4TlPh2]+ was also synthesised.
