A one-pot synthesis of syn-2,3-epoxyalcohols from alpha,beta-unsaturated ketones
(Serbian Chemical Soc, Belgrade, 1998)
Facile one-pot synthesis of syn-2,3-epoxyalcohols from a,P-unsaturated ketones was achieved by consecutive addition of diisobutylaluminium hydride and t-butyl hydroperoxide.
mer-[2'-(2-Benzoyl-1-methylethylidene)-1-napthtohydrazido(2-)](methanol)-cis-dioxo-molybdenum(VI)
(Munksgaard Int Publ Ltd, Copenhagen, 1996)
In the molecule of the title compound, [MoO2(L)(CH3-OH)] [L is the dianion of 2'-(2-benzoyl-1-methylethylidene)-1-naphthohydrazide, C21H16N2O2], the Mo atom displays distorted octahedral coordination geometry, being ...
Potassium 3-dithiocarboxy-3-aza-5-aminopentanoate dihydrate

The synthesis and crystal structure of the title compound, K+. C5H9N2O2S2-. 2H(2)O, are described. The structure consists of potassium cations, 3-dithiocarboxy-3-aza-5-aminopentanoate anions and molecules of water. The ...
A new synthesis of alpha-tetralones.
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
alpha-tetralones 8a-j can be prepared by radical cyclisation, in the presence of stoichiometric amounts of lauroyl peroxide, of xanthates 5a-j obtained by an intermolecular addition of substituted S-phenacyl xanthates 4a-c ...
Free radical phenylthio group transfer to nonactivated delta-carbon atom in the photolysis reactions of alkyl benzenesulfenates
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
A free radical phenylthio group transfer from oxygen to the non-activated delta-carbon atom was achieved by irradiation of alkyl benzenesulfenates 1 in the presence of hexabutylditin, and delta-phenylthio alcohols 2 were ...
Free radical mediated construction of small ring compounds: The double annulation of bicyclo[3.1.0]hex-2-enes
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
A free radical approach to fused cyclopropane derivatives is described. Homolytic decomposition of thiohydroxamic esters 4a-e in the presence of dimethyl acetylendicarboxylate affords bicyclo[3.1.0]hex-2-enes 6a-e in ...
Effect of Electronegativity of Donor Atoms on R F Values of Tris(15-diketonato) Complexes of Cobalt(Ill), Chromium(Ill) and Ruthenium(Ill) by Thin-Layer Chromatography on Silica Gel
(Springer, 1993)
The effect of the electronegativity of donor atoms on
R F values obtained by TLC on silica gel was investigated
with two series of complexes of the type [M(acac)3_ n
!phacphac)n ] and [M(acac)3_n(phacphSac)n], where ...
Investigation of the origin of Aleksinac oil shale organic matter
(Journal of the Serbian Chemical Society, 1996)
In order to determine the origin of organic matter of Aleksinac oil shale (the village of Subotinac) a detailed GC-MS analysis of biological markers such as steranes, diterpanes and triterpanes was carried out. Also, ...
