Described herein is an effective and practical modular flow design for the meta-selective C-H arylation of anilines. The design consists of four continuous-flow modules (i.e., diaryliodonium salt synthesis, meta-selective C-H arylation, inline copper extraction, and aniline deprotection) which can be operated either individually or consecutively to provide direct access to meta-arylated aniline...

In the title picrate salt of a dihalogenated aniline derivative, C(6)H(6)ClF(+)·C(6)H(2)N(3)O(7) (-), the intra-cyclic C-C-C angles in the picrate anion cover a broad range [111.95 (12)-125.38 (13)°], while those in the aromatic cation span a much narrower range [118.25 (14)-122.33 (13)°]. In the crystal, classical N-H⋯O hydrogen bonds, as well as C-H⋯O contacts, connect the ions into layers pa...

the use of appropriate level of theories for studying weak van der waal interactions such as 8-8stacking interactions of aromatic molecules has been an important aspect, since the high levelmethods have limitations for application to large molecules. the differences in the stacking energiesof various aromatic molecular structures are found significant. it is also very important for identifyingt...

a type of novel hypercross-linked fiber adsorbent was obtained by sulfonation and cross-linking reaction of polypropylene fiber grafted styrene-divinylbenzene. the aim of the fiber sulfonation and cross-linking method was to prepare rigid three dimensional networks in the entire fiber and change the ion exchange capacity of fiber. the hypercross-linked fiber adsorbent possesses a principally di...

N-(n-Dec-yl)-4-nitro-aniline, C(16)H(26)N(2)O(2), crystallizes with two essentially planar mol-ecules in the asymmetric unit. The decyl chains are fully extended in an anti conformation. The mol-ecules pack in planar layers, within which mol-ecules are linked into chains by two approximately linear N-H⋯O hydrogen bonds between the amine N atom and one O atom of the nitro group of an adjacent mo...

Complex compounds of platinum metals Ru(III), Rh(III), Os(IV), Ir(IlI) and Pt(IV) with the bidentate Schiff base ligand derived by the condensation of phenyl glyoxal with p-diethylamino aniline have been prepared and characterized. All the complexes are stable at room temperature. The complexes of Ru(III) and Os(IV) are Paramagnetic and the other complexes of Rh(III), Ir(III) and Pt(IV) are dia...

In this letter, we propose a novel, ultrafast, efficient molecular switch whose switching mechanism involves the electric field-driven intramolecular proton transfer. By means of ab initio quantum chemical calculations and on-the-fly dynamics simulations, we examine the switching performance of an isolated salicylidene aniline molecule and analyze the perspectives of its possible use as an elec...
