Oxidative fragmentation of 5-hydroxy-1-oxo-5α-cholestan-3β-yl acetate / Oksidativne fragmentacije 5-hidroksi-1-okso-5α-holestan-3β-il-acetata
(Serbian Chemical Society, 2003)
5-hydroxy-1-oxo-5α-cholestan-3β-yl acetate (11) was prepared in 5 steps starting from (E)-3β-acetoxy-5,10-seco-1(10)-cholesten-5-one (6). Treatment of the 1-oxo-5-hydroxy derivative 11 with lead tetraacetate (LTA) (under ...
Morphology of Ni-Mo-O alloy powders electrodeposited from ammonium sulfate solutions / Morfologija prahova Ni-Mo-O legura istaloženih elektrohemijskim postupkom iz rastvora amonijum sulfata
(Belgrade, Serbia : Engineering Society for Corrosion, 2008)
The electro deposition of the Ni-Mo-O alloy powders from ammonium sulfate containing electrolytes of different Ni/Mo ions concentration ratios was investigated by the polarization measurements. In all electrolytes similar ...
