Amplifying fluorescent conjugated polymer sensor for singlet oxygen detection
Wang, Chun-Han,Nesterov, Evgueni E.
, p. 8955 - 8958 (2019)
A "higher energy gap" concept was applied towards designing an efficient turn-on amplifying sensor for singlet oxygen-an important biomedical and environmental monitoring analytical target. The concept is based on modulation of intramolecular energy trans

supporting information, p. 9674 - 9685 (2021/06/09)
Two highly efficient metal-organic framework catalysts TJU-68-NHPI and TJU-68-NDHPI have been successfully synthesized through solvothermal reactions of which the frameworks are merged with N-hydroxyphthalimide (NHPI) units, resulting in the decoration of pore surfaces with highly active nitroxyl catalytic sites. When t-butyl nitrite (TBN) is used as co-catalyst, the as-synthesized MOFs are demonstrated to be highly efficient and recyclable catalysts for a novel three-phase heterogeneous oxidation of activated C?H bond of primary and secondary alcohols, and benzyl compounds under mild conditions. Based on the high efficiency and selectivity, an environmentally benign system with good sustainability, mild conditions, simple work-up procedure has been established for practical oxidation of a wide range of substrates.

A facile, regioselective and controllable bromination of aromatic amines using a CuBr2/Oxone system
Li, Xin-Le,Wu, Wei,Fan, Xin-Heng,Yang, Lian-Ming
, p. 12091 - 12095 (2013/09/02)
A combination of cupric bromide and Oxone serves as a facile, mild and effective reagent for the bromination of aromatic amines. Primary, secondary and tertiary aromatic amines are all suitable substrates. The reaction possesses high regioselectivity and functional group tolerance, and mono- and multi-brominated products can be obtained controllably in moderate to excellent yields.

Condensed thiophenes and selenophenes: Thionyl chloride and selenium oxychloride as sulfur and selenium transfer reagents
Amaresh, Ramiya R.,Lakshmikantham,Baldwin, Jeffrey W.,Cava, Michael P.,Metzger, Robert M.,Rogers, Robin D.
, p. 2453 - 2458 (2007/10/03)
3,4-Cyanomethyl substituted thiophenes reacted with thionyl chloride in the presence of base to give dicyano substituted thieno(3,4-c)thiophenes. The use of selenium oxychloride furnished the corresponding cyano substituted seleno(3,4-c)thiophene. 1,2-Phenylenediacetonitriles gave the corresponding cyano substituted benzo(c)thiophenes and benzo(c)selenenophenes, respectively, upon reaction with thionyl chloride and selenium oxychloride in the presence of base.
Synthesis and Rigid Conformers of 14,15-Dimethyl-2,11-dithia(1,3)(1,4)cyclophane and 12,13-Dimethyl(1,3)(1,4)cyclophane
Lai, Yee-Hing,Yap, Angeline Hui-Tin
, p. 1373 - 1377 (2007/10/02)
The dithiacyclophane 4 was synthesized from 2,3-dimethylaniline in seven steps.Only the conformer 5b was isolated.Photodesulfurization of 4b however resulted only in the isolation of the cyclophane 2a indicating an abrupt change in conformational preferen
Method for the manufacture of P-bromodimethyl aniline
-
, (2008/06/13)
Para-bromodimethyl aniline of a high purity at high yields is obtained by the direct bromination of N,N'-dimethyl aniline with bromine in the presence of a solvent. The temperature which prevails during the reaction may be up to the reflux of the solvent used. The solvent consists of at least one halogenated hydrocarbon having the formula RXnwherein: R is a straight or branched aliphatic hydrocarbon having 1 to 12 carbon atoms, X is bromine or chlorine and n is between 1 and 4, with the proviso that when n is 4, the solvent is CCl4.
