Alkynes as Synthetic Equivalents of Ketones and Aldehydes: A Hidden Entry into Carbonyl Chemistry
Molecules, 2019 The high energy packed in alkyne functional group makes alkyne reactions highly thermodynamically favorable and generally irreversible. Furthermore, the presence of two orthogonal π-bonds that can be manipulated separately enables flexible synthetic ...

Iridium-Catalyzed and pH-Dependent Reductions of Nitroalkenes to Ketones
Molecules, 2022 A highly chemoselective conversion of α,β-disubstituted nitroalkenes to ketones is developed. An acid-compatible iridium catalyst serves as the key to the conversion.

Degradation of epoxy coatings under gamma irradiation [PDF]
, 2013 Epoxy networks based on Diglycidyl ether of bisphenol A (DGEBA) and cured with Jeffamines (POPA) or polyamidoamine (PAA) were gamma irradiated at 25 1C in air. Dose rates of 50, 200 or 2000 Gy h- 1 for doses up 100 kGy were used.

Highly substituted benzannulated cyclooctanol derivatives by samarium diiodide-induced cyclizations
Beilstein Journal of Organic Chemistry, 2010 A series of γ-oxo esters suitably substituted with various styrene subunits was subjected to samarium diiodide-induced 8-endo-trig cyclizations. Efficacy, regioselectivity and stereoselectivity of these reactions via samarium ketyls strongly depend on ...

Naturally occurring long-chain β-hydroxyketones
Journal of Lipid Research, 1971 A fraction comprising about 0.7% of the extractable surface lipids of cabbage (Brassica oleracea) leaves was isolated and identified as a mixture of isomeric βhydroxyketones consisting mainly of 14-keto-16-hydroxynonacosane and 15-keto-13 ...
