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.

Thermal decomposition ofC-iodotetrazoles

AbstractThermal decomposition of 1-substitutedC-iodotetrazoles in melt and solutions has been investigated. Thermal stabilities, kinetic and activation parameters, and compositions of products of thermolysis ofC-iodotetrazolcs depend on the substituent nature.

The application of laser microprobe mass analysis to the study of biological material

AbstractLaser microprobe mass analysis (LAMMA) is an investigational method which is a powerful tool for the identification and quantitation of various elements present in small volumes of tissue. LAMMA is highly sensitive and capable of rapidly detecting concentrations of 1–3 p.p.m.

On the plasma chemistry of the C/H system relevant to diamond deposition processes

AbstractThe chemistry of hydrogen-rich hydrocarbon-hydrogen mixtures is of primary interest for the understanding of the low-pressure synthesis of diamond. We per formed experiments under well-defined conditions like temperature, pressure, initial gas composition, etc.

Post-translational proteolytic processing and the isolectins of lentil and other Viciae seed lectins

AbstractElectrospray mass spectrometry was used to identify precisely the proteolytic cleavage points within, and at the C-termini of, the proprotein forms of four Viciae lectins that give rise to their two-chain forms.

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.
