Mechanistic study of substituted 5-Hexen-1-YL radicals : evaluation of capto-dative stabilization effects
(1985)
Three aliphatic bromides, 6-bromo-1-cyano-1-methoxy-1-hexene, 6-bromo-1-cyano-1-hexene and 6-bromo-1-methoxy-1-hexene, designed for the introduction of capto-dative stabilization effect into the well known 5-hexen-1-yl ...
Functionalization of polyolefins : entrapment of functionalized ethylene oligomers in polyethylene
(1985)
Functionalization of polyethylene by entrapment of functionalized ethylene oligomers in precipitates of polyethylene is described. The details of this entrapment process, which is an alternative to harsh, unselective ...
A portable multichannel flourescence spectrophotometer for characterization of marine phytoplankton populations
(1985)
The rapid and sensitive monitoring of natural phytoplankton populations is commonly performed by detection of vivo fluorescence. However, the non-scanning fluorescence spectrometers that are commonly used cannot easily ...
The catalytic behaviors of lanthanum and neodymium oxides for dehydrogenation/dehydration of ethanol
(1985)
The ethanol dehydrogenation and dehydration reactions have been employed to investigate the nature and behavior of catalytically active sites on lanthanum and neodymium sesquioxides. In support of this objective, x-ray ...
The analysis of mixed associations of aqueous nucleoside solutions
(1985)
Two similar chemical interactions were studied: (1) that between two naturally occurring nucleosides found in deoxyribonucleic acids, 2'-deoxyadenosine and thymidine; and (2) between the nucleoside 2'-deoxyadenosine and ...
Two-photon excitation spectroscopy of some polynuclear aromatic compounds
(1985)
Two-photon excitation spectra were taken for the following compounds: phenanthrene, 3,4-benzophenanthrene, triphenylene, chrysene, pyrene, and tetracene. The samples were dissolved in n-alkane solvents and the spectra were ...
Studies directed toward stereoselective synthesis of 1,3-amino alcohols via intramolecular amidomercuration
(1985)
The cyclization of the benzyl carbamate of 6-hepten-2-amine (31) with mercuric trifluoroacetate in nitromethane over a period of 20 h afforded, after borohydride reduction of the organomercurial, the benzyl carbamate of ...
Methods for polynuclear aromatic hydrocarbon determination in air samples using polar-bonded phase HPLC and GC-MS with application to oil refinery samples
(1985)
The first part of this work deals with the development of accurate and reliable procedures for collection and analysis of polynuclear aromatic hydrocarbons (PNAs). The second part shows the application of these procedures ...
