    Saturated 2D-LIF of OH and 2D determination of effective collisional lifetimes in atmospheric pressure flames (1991)

    Notes: Abstract Saturation of two-dimensional laser-induced fluorescence is demonstrated using the coincidence between the strong 0–0 vibrational transition of OH around 308 nm and the emission of a tunable XeCl excimer laser. The 2D images were insensitive to variations in the laser power, implying reduced sensitivity to quenching processes. The ratio of the 2D images in the linear and saturated regimes show two-dimensional variations in the saturation intensity. Since saturation intensity is proportional to the quenching rate, this novel method allows one to check for variations in collisional lifetimes across the flame.

    Notes: A new merocyanine was prepared by addition of the pyrrolidine enamine of N-ethoxycarbonylpyrrolidine-3-one to 1-octyne-3-one. This addition was regioselective (with an unexpected C-4 alkylation of the pyrrolidinone-3-enamine) and stereospecific (exclusively trans addition to the triple bond). The structure and conformational equilibrium were studied by high resolution proton magnetic resonance (NOE and variable temperature effects). Activation parameters ΔH*, ΔS* and ΔG* are given, and the behaviour on protonation examined.

    Description / Table of Contents: Bis-phenylphosphino-methylpyridine-(2) (PhPMP) gives with NiII salts 1,2-chelates. The chloro and thiocyanato chelate have octahedral, the perchlorate a planar-quadratic structure. Coordination number 5 is discussed for the corresponding bromo and iodo complexes.CoII-1,2-chelates are also formed with PhPMP. The chloro, bromo, and thiocyanato complexes are all of high-spin type, having an octahedral structure. The chelates from CoII iodide and perchlorate show reduced paramagnetism. In Co(PhPMP)2(ClO4)2 one perchlorate group appears to have a monodentate ligand function.
    Notes: Bisphenylphosphino-methylpyridin-(2) (PhPMP) bildet mit Nickel(II)-Salzen Chelate vom 1,2-Typ. Dabei kommen dem Chloro- und Rhodanokomplex eine oktaedrische, dem Perchlorat eine planar-quadratische Struktur zu. Für den Bromo- und Jodokomplex wird die Koordinationszahl 5 diskutiert. Kobalt(II)-Verbindungen geben mit PhPMP gleichfalls 1,2-Chelate. Der Chloro-, Bromo- und Rhodanokomplex gehören dem High-spin-Typ an und besitzen eine oktaedrische Struktur. Die vom Kobalt(II)-jodid bzw. -perchlorat abgeleiteten Chelate zeigen reduzierten Paramagnetismus. Im Co(PhPMP)2(ClO4)2 fungiert das Perchlorat z. T. als einzähliger Ligand.

    Description / Table of Contents: On the Anomal Magnetically Behaviour of Diethylphosphino Methylpyridine-(2) Complexes of 3d IonsDiethylphosphino methylpyridine-(2) forms 1,2-complexes with nickel(II) and cobalt(II). In these complexes depending on the nature of anionic ligands which are present in addition, the central atoms have the coordination numbers 4, 5 or 6.“Ni(Et2PMP)2Cl2” and “Ni(Et2PMP)2Br” are magnetically anomal. They are inter-allogones, probably containing five-coordinate nickel(II) species of the low-spin and the high-spin type.The cross-over between high-spin and low-spin types of five-coordinate nickel(II) complexes, observed by Sacconi at the donor atom set N2P2Cl, has been verified. With five-coordinate cobalt(II) complexes this cross-over was observed at the same donor atom set.Et2PMP forms a diamagnetic, octahedral 1, 3-complex with iron(II) and a tetrahedral 1,2-complex with zinc(II).
    Notes: Diäthylphosphino-methylpyridin-(2) bildet mit Nickel(II)- bzw. Kobalt(II)-Salzen 1,2-Komplexe, in denen die Zentralatome je nach den zusätzlich vorhandenen anionischen Liganden die Koordinationszahlen 4, 5 oder 6 haben.„Ni(Et2PMP)2Cl2“ und „Ni(Et2PMP)2Br2“ verhalten sich magnetisch anomal und werden auf Grund ihres physikalischen Verhaltens als Interallogone angesprochen, die fünffach-koordinierte Nickel(II)-Spezies vom Low-Spin- und vom High-Spin-Typ nebeneinander enthalten.Der von Sacconi für fünffach-koordinierte Nickel(II)-Komplexe gefundene übergang von High-Spin- zu Low-Spin-Typen beim Haftatomsatz N2P2Cl konnte bestätigt werden. Für die fünffach-koordinierten Kobalt(II)-Komplexe wurde der übergang beim gleichen Haftatomsatz beobachtet.Mit Eisen(II) bildet Et2PMP einen diamagnetischen, oktaedrischen 1,3-Komplex, mit Zink(II) einen tetraedrischen 1,2-Komplex.
