East China Normal University , commonly referred to as ECNU, is a comprehensive research university in Shanghai, China. Established in 1951, it is the first national normal university of the People's Republic of China.Originally founded to train school teachers, the University is now an institution training researchers, professors, high-level civil servants, as well as business and political leaders. Sponsored by the national program "Project 211" and "Project 985", the university is a staunch force in the nation's research in the humanities, social science and technology innovation, and is reputed to be the "Columbia of the East". ECNU is ranked 67th in Asia according to the Times Higher Education Asia University Rankings in 2014, while the Leiden Ranking considered it 280th worldwide in 2013.ECNU is an institution of higher education with global impact. China's first Sino-US higher education institute – New York University Shanghai – is jointly operated by New York University and ECNU. King's College London, the University of California, as well as the University of Manchester hold their international summer schools at ECNU each year.Since 2013, the University officially changed its French name to École normale supérieure de l'Est de la Chine, to put forward the academic cooperation between ECNU and the École Normale Supérieure Group in France. And the ENS-ECNU Joint Graduate School was formally established in June 2005. Wikipedia.

Allenes are the simplest class of cumulenes, with two contiguous C=C bonds, and show unique physical and chemical properties. These features make allenes particularly attractive in modern organic chemistry. In this Review, attention is paid to the advances made in catalytic asymmetric synthesis and natural product syntheses based on well-established reactions of allenes, such as propargylation, addition, cycloaddition, cycloisomerization, cyclization, etc., with or without catalysts. Their versatile reactivity, substituent-loading ability, axial to center chirality transfer, and controllable selectivity allow access to target molecules by unique and efficient approaches. The main topics in this Review are presented with selected examples from 2003 to 2011. Creative and easy syntheses of chiral compounds and natural products are possible by using allenes. These compounds display exceptional physical and chemical properties, and thus offer new possibilities in catalytic asymmetric synthesis and the total synthesis of natural products. The remarkable progress made in these two topics is summarized selectively in this Review. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source

Copper salts have been developed as versatile catalysts for oxidative coupling reactions in organic synthesis. During these processes, Cu-catalysts are often proposed to serve as a one-electron oxidant to promote the single-electron transfer process. Recently, the transition-metal catalyzed direct dehydrogenative transformation has attracted considerable attention. This tutorial review summarizes the recent advances in the copper-catalyzed dehydrogenative functionalization via a single electron transfer (SET) process achieving C-C, C-N, C-O, C-halogen atoms, C-P, and N-N bond formation. © The Royal Society of Chemistry 2012.

The spherically symmetric static solutions are searched for in some f(T) models of gravity theory with a Maxwell term. To do this, we demonstrate that reconstructing the Lagrangian of f(T) theories is sensitive to the choice of frame, and then we introduce a particular frame based on the conformally Cartesian coordinates. In this particular frame, the existence conditions of various solutions are presented. Our results imply that only a limited class of f(T) models can be solved in this frame. For more general models, the search for spherically symmetric static solutions is still an open and challenging problem, hopefully solvable in other frames. © 2011 American Physical Society. Source
