The cover art represents how the Z-isomers of the meta-substituted azobenzene macrocycles show thermal relaxations slower than those of para-substituted compounds, and that electron-donating groups led to a faster relaxation. The cover art was created by Souvik Ghosh. View the article. Journal of Materials Chemistry B is a Transformative Journal and Plan S compliant. Impact factor: 7.0*. Time to first decision (all decisions): 12.0 days**. Time to first decision (peer-reviewed only): 37.0 days***. Editor-in-Chief: Jeroen Cornelissen. Indexed in MEDLINE.The development of catalytic systems for the controlled oxidn. of C-H bonds remains a highly sought-after goal in chem. owing to the great utility of such transformation toward expediting the synthesis and functionalization of org. mols. Cytochrome P 450 monooxygenases are the catalysts of choice in the biol. world for mediating the oxidn. of …Pages: 4117-4120. First Published: 22 June 2017. A cross-dehyrogenative coupling of 1,4-dimethoxybenzenes with sodium and lithium sulfinates is reported. The reaction is mediated by Mn (OAc) 3 and provides various aryl sulfones in high yields. HFIP = 1,1,1,3,3,3-hexafluoroisopropanol, M = Li, Na. Abstract.Front Cover: A Diversity-Oriented Approach to Large Libraries of Artificial Macrocycles (Eur. J. Org. Chem. 17/2021) Dr. Serhii H.

Synthesis and Properties of ABA Amphiphiles. Yiyan Chen; and ; Gregory L. Baker; View Author Information.We report that a combination of DPPF (1,1-bis(diphenylphosphino)ferrocene) and Pd(dba)2 leads to the amination of aryl triflates, a reaction that allows for the conversion of phenols to arylamines. A combination of BINAP and Pd(dba)2 also catalyzes the amination of aryl triflates, but P(o-tolyl)3 complexes were not effective catalysts. In some cases, slow ….
