Excited state spectroscopy of para di-substituted benzenes in a supersonic beam using resonant two photon ionization
(Elsevier, 1986)
Excited state vibronic spectra of p-aminophenol, p-cresol, p-fluoroaniline, p-fluorophenol, hydroquinone and p-toluidine have been obtained using resonant two photon ionization supersonic beam mass spectrometry. Despite ...
Intramolecular azide-diene cycloadditions. An approach to fused bicyclic 3-pyrrolines based on a one-pot nitrene-diene cycloaddition equivalent.
(Elsevier, 1986)
Cyclization of heterosubstituted [omega]-azidodienes 11 provides fused bicyclic 3-pyrrolines 12 in one operation. These pyrrolines are potentially useful intermediates for natural products synthesis, as illustrated by ...
Thermophysics of metal alkanoates VI. Heat capacities and thermodynamic properties of lithium n-pentanoate and n-heptanoate
(Elsevier, 1986-12)
The adiabatic calorimetric study (at 5 to 350 K) of lithium n-pentanoate and n-heptanoate proved that solid-state transitions occur at Ttrs/K = 209.31 and 319.06 in the former salt, and at Ttrs/K = 317.08 in the latter ...
The exchange reaction of tetramethyldipnictogens with dimethyldichalcogenides
(Elsevier, 1986-07-15)
Tetramethyldipnictogens Me4E2 (E = P, As, Sb, Bi) undergo exchange reactions with dimethyldichalcogenides Me2A2 (A = S, Se, Te) to produce the corresponding (dimethylpnicto)methylchalcogenides Me2EAMe. These compounds have ...
Silver(I) sulfide: Ag2S Heat capacity from 5 to 1000 K, thermodynamic properties, and transitions
(Elsevier, 1986-04)
The heat capacity of Ag2S has been measured by adiabatic-shield calorimetry from 5 to 1000 K. The heat capacity increases regularly up to about 445 K where the pre-transitional contribution causes rapidly rising values. ...
Report on the catalytic activity of 6-heteropolymolybdates as potential Fischer-Tropsch synthesis catalysts
(Elsevier, 1986-02-14)
Unsupported and supported decomposition products of 6-heteropolymolybdates were tested as possible Fischer-Tropsch synthesis catalysts. Depending on the heteroatom, the activity changes significantly and the best supported ...
The mechanism of the oxidation of propene to acrolein over copper oxide
(Elsevier, 1986-05)
The oxidation of stereo-labeled propene to acrolein over copper oxide was studied to obtain information about the nature of the intermediates involved in the second hydrogen abstraction and oxygen incorporation process. ...
The exchange reaction of tetramethyl-diphosphine, -diarsine, -distibine and -dibismuthine
(Elsevier, 1986-04-08)
Tetramethyldiphosphine and tetramethyldiarsine undergo an exchange reaction to give (dimethylarsino)dimethylphosphine. The equilibrium constant at 25[deg]C in benzene is found to be 0.26. Similarly, mixtures of ...
Additions of allylboronates to sulfenimides
(Elsevier, 1986)
The addition of allyllioronates to sulfenimines gives homoallylsulfenamides which are potentially versatile Intermediates for alkaloid synthesis.
Radiative properties of an electrically-vaporized thin film plasma in an external magnetic field
(Elsevier, 1986)
An external magnetic field of a few kilogauss is used to alter significantly the radiative properties of the plasmas generated by the capacitive discharge vaporization ofthin Ag films. The magnetic field is generated by ...
