Transition metal carbenes with polarised-covalent M = C double bonds have been known for decades, but it was not until 1981 that the first U = C double bond was isolated in the uranium(IV)–carbene complex [U(η5-C5H5)3{C(H)PMe2Ph}]22. After initial advances23,24,25,26,...
Several inducers with intermediate effectiveness were hydrogenated in low yield with accompanying metabolism of other functional groups. Overall, caffeate (3,4-dihydroxycinnamate) was the best inducer. 展开 关键词: Biocatalytic hydrogenation C– C double bond reduction Inducer structure Aceto...
Regioselective vicinal diamination of carbon–carbon double bonds with two different amines is a synthetic challenge under transition metal-free conditions, especially for the synthesis of trifluoromethylated amines. However, the synthesis of ethylene di

摘要: Double bonds activated by the electron withdrawing group(s) are cleaved with the reagent system consisting of a hard Lewis acid and ethanethiol to give dithioacetals.关键词: thio compounds (benzene compounds DOI: 10.1016/0040-4039(81)80019-6 ...
A survey of carbon–carbon double bond lengths in transition metal vinyl complexes reveals a number of complexes with surprisingly short C C bonds. Accurate calculations with restricted Hartree–Fock (RHF) and density functional theory (DFT) methods on three examples with extremely short C C double...
double bond of (groupO2) ketones, lactones, anhydrides, etc.; the 531.9 eV to the C–O–C in furans or keto-enolic tautomers of groupO3; the 532.7 eV to the phenolic group (groupO4), and the 534.2 eV to the carboxylic group (groupO6). Consistent with the TPDE profile ...
