Quality Control of Benzoic anhydride. Recently I am researching about OXIDATION; ALKENES; SELECTIVITY; OLEFINS; AMIDYL, Saw an article supported by the National Basic Research Program of ChinaNational Basic Research Program of China [973-2015CB856600]; National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [21532009, 21821002, 21790330, 21761142010]; Science and Technology Commission of Shanghai MunicipalityScience & Technology Commission of Shanghai Municipality (STCSM) [17XD1404500, 17QA1405200, 17JC1401200]; Strategic Priority Research ProgramChinese Academy of Sciences [XDB20000000]; Key Research Program of Frontier Science [QYZDJSSW-SLH055]; Youth Innovation Promotion Association of the Chinese Academy of Sciences [2018292]; Research Grants Council of Hong KongHong Kong Research Grants Council [HKUST 16304416, 16304017]. Published in NATURE PUBLISHING GROUP in LONDON ,Authors: Li, JY; Zhang, ZH; Wu, LQ; Zhang, W; Chen, PH; Lin, ZY; Liu, GS. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride
Methods for selective C-H bond functionalization have provided chemists with versatile and powerful toolboxes for synthesis, such as the late-stage modification of a lead compound without the need for lengthy de novo synthesis(1-5). Cleavage of an sp(3) C-H bond via hydrogen atom transfer (HAT) is particularly useful, given the large number of available HAT acceptors and the diversity of reaction pathways available to the resulting radical intermediate(6-17). Site-selectivity, however, remains a formidable challenge, especially among sp(3) C-H bonds with comparable properties. If the intermediate radical could be further trapped enantioselectively, this should enable highly site- and enantioselective functionalization of C-H bonds. Here we report a copper (Cu)-catalysed site- and enantioselective allylic C-H cyanation of complex alkenes, in which a Cu(ii)-bound nitrogen (N)-centred radical plays the key role in achieving precise site-specific HAT. This method is shown to be effective for a diverse collection of alkene-containing molecules, including sterically demanding structures and complex natural products and pharmaceuticals.
