Application to Microwave-Based Heck Reaction. [作者：Niembro, Sandra;Shafir, Alexandr;Vallribera, Adelina;Alibes, Ramon;,期刊：Organic Letters, 页码：3215-3218 , 文章类型： 研究论文，,卷期：2008年10-15] Phosphine-free palladium nanoparticles were embedded in a fluorous org.-inorg. hybrid material prepd. by the sol-gel process. The use of this solid-supported palladium catalyst system in the Heck coupling reaction under... On the Actual EPR Detection of Thioacyl Radicals. [作者：Alberti, Angelo;Benaglia, Massimo;Guerra, Maurizio;Gulea, Mihaela;Macciantelli, Dante;Masson, Serge;,期刊：Organic Letters, 页码：3327-3330 , 文章类型： 研究论文，,卷期：2008年10-15] The direct EPR detection of thioacyl radicals has been reported only once, while thioacyl nitroxides remain an elusive species. We failed to detect the thioacyl radicals from two thioaldehydes and from phosphoryldithiof... [3,3]-Sigmatropic Shifts of N-Allylhydrazones: Quantum Chemical Comparison of Concerted and Radical Cation Pathways. [作者：Siebert, Matthew R.;Tantillo, Dean J.;,期刊：Organic Letters, 页码：3219-3222 , 文章类型： 研究论文，,卷期：2008年10-15] N-Allylhydrazones are reported to undergo an elaborate [3,3]-sigmatropic shift/N2 extrusion sequence. Both concerted and radical cation pathways for the [3,3]-sigmatropic shift of several N-allylhydrazones were investig... Rh-catalyzed asymmetric hydrogenation of g-phthalimido-substituted a,b-unsaturated carboxylic acid esters: An efficient enantioselective synthesis of b-aryl-g-amino acids. [Erratum to document cited in CA148:055346]. [作者：Deng, Jun;Duan, Zheng-Chao;Huang, Jia-Di;Hu, Xiang-Ping;Wang, Dao-Yong;Yu, Sai-Bo;Xu, Xue-Feng;Zheng, Zhuo;,期刊：Organic Letters, 页码：3379-3379 , 文章类型： 研究论文，,卷期：2008年10-15] On page 4827, in Table 2, the assignment of the abs. configuration in entries 1, 6, and 9 was incorrect; the compds. with (-) optical rotation should have (S), not (R), configuration. The cor. table has been reproduced.... Heteroaryl-Substituted C3-Bridged Oligopyrroles: Potential Building Subunits of Anion-Responsive p-Conjugated Oligomers. [作者：Maeda, Hiromitsu;Mihashi, Yuta;Haketa, Yohei;,期刊：Organic Letters, 页码：3179-3182 , 文章类型： 研究论文，,卷期：2008年10-15] Acyclic anion receptors (BF2 complexes of dipyrrolyldiketones) with heteroaryl moieties synthesized by using cross-coupling reactions have unique electronic states, as obsd. in UV/vis absorption spectra. Among heteroaryl...
