Free radical carbocyclic ring reconstruction
(Tetrahedron Letters, 1986)
Alkenyl radical generated by β-fragmentation of tertiary cyclohexyloxy radical with carbocyclic ring opening, possessing a suitably located olefinic double bond, undergoes to the intramolecular 5-exo-trigonal cyclization ...
Free radical annulation of cyclopentane ring
(Tetrahedron Letters, 1986)
Homoallyl radical, e.g. 2, reacts with an electron-deficient olefinic bond 1 with a new CC bond forming and arising of a 5-hexenyl radical 3 which further undergoes to 5-exo-trigonal cyclization with a cyclopentane ring ...
Local electron density models for Tl to Pb conversion in lorandite
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detecto, 1988)
The nuclear conversion of 205Tl to 205Pb by neutrino capture, lorandite (TlAsS2) converts into Pb-bearing lorandite (Tl1-xPbxAsS2) where x is a very small number. Having used a highly simplified cluster model of lorandite, ...
Correlative geochemical study of crude oils from southeastern and southern parts of the Pannonian Basin
(Organic Geochemistry, 1988)
Several crude oils from the southeastern Yugoslav part of the Pannonian Basin are correlated for the first time on the basis of many bulk and specific parameters. The investigations involved 15 oils from oil-gas fields A ...
