Intramolecular cyclization of organometallic compounds represents
a promising tool for synthesis. The reaction involves exothermic
consumption of intramolecular double bonds via insertion
into a carbon metal sigma bond. This represents an intramolecular
example of the reaction type responsible for metal catalyzed polymerization
of olefins.
Organolithium reagents were found to cyclize...
The oxidation of triethylamine by the two electron oxidant
thallium(III) chloride was studied and the results compared to those
when triethylamine is oxidized by copper(II) halides. This study
requires anhydrous conditions since in an aqueous system thallium(III)
chloride is extensively hydrolyzed and triethylamine causes
precipitation of thallium(III) oxide. Most of...
Interesting rovibrational characteristics of two D_(3h) oblate symmetric top molecules were studied. Hamiltonian models for the fine rovibrational level structure of [1.1.1]propellane (propellane) were obtained for many low-lying modes. Ground state parameters (GSP) that are not exclusively K^(2n) dependent were obtained. Initially, the GSP were used in conjunction with density...
The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...
An improved procedure for the preparation of β-(3-cyclohexenyl) propionic acid from 4-vinylcyclohexene was developed. The
Friedel-Crafts cyclization of β-(3-(3-cyclohexenyl) propionyl chloride
with aluminum chloride was shown to give one bicyclic chlorine
containing ketone in 41% yield. This ketone was identified by a combination of spectral and chemical methods as a...
