The preparation of multidimensional nano- and micro structures, in particular suprastructures with well-defined morphol. and bright emissions, is a challenging task in supramol. assembly. For this purpose, a new type of amphiphilic diplatinum complexes is presented as an excellent building block to assemble into highly phosphorescent nanofibers by supramol. Pt···Pt interactions. These organoplatinum supramol. fibers are further used as a pre-organized monomer reservior for the metal ion-triggered post-transformation into crystalline nanoneedles, nanorods, nanobunches, microplates, and microflowers with controllable morphol. and bright phosphorescence. A reverse transformation of the obtained nanorods into nanofibers is demonstrated with the aid of ethylenediamine tetraacetic acid. In contrast, the direct treatment of diplatinum complexes with different metal ions fails to give well-defined nano and microstructures, suggestive of the pre-organized role of nanofibers for the morphol. transformation. Preliminary applications of these nano- and suprastructures in sensing temperature and organic vapors by emission signal changes are demonstrated. In contrast to the conventional hierarchical assembly, the pre-organized monomer-reservoir strategy disclosed in this study offers a versatile method for the synthesis of organic nano and suprastructures with multidimensional morphol. and controllable emission properties.

Mizoguchi, Haruki; Seriu, Masaya; Sakakura, Akira published the artcile< Synthesis of functionalized cyclopropylboronic esters based on a 1,2-metallate rearrangement of cyclopropenylboronate>, Category: ethers-buliding-blocks, the main research area is crystal structure mol optimized seleno cyclopropyl boronic ester preparation; stereoselective metalate rearrangement cyclopropenyl boronate.

A procedure converting tribromocyclopropane to densely functionalized β-selenocyclopropylboronic ester using the 1,2-metalate rearrangement of a boron ate-complex has been developed. Treatment of an in situ-generated cyclopropenylboronic ester ate-complex with phenylselenenyl chloride triggered stereospecific rearrangement to produce functionalized cyclopropanes. DFT calculations for 1,2-metalate rearrangement suggested that the reaction proceeds through a seleniranium intermediate.

Karmakar, Ujjwal; Hwang, Ho Seong; Lee, Yunjeong; Cho, Eun Jin published the artcile< Photocatalytic para-Selective C-H Functionalization of Anilines with Diazomalonates>, Synthetic Route of 10541-78-3, the main research area is photocatalytic para selective alkylation aniline diazomalonate.

Visible-light-induced para-selective C-H functionalization of anilines over N-H insertion was developed using diazomalonates with the help of an Ir(III) photocatalyst. The para-selective radical-radical cross coupling proceeded via C-centered radical intermediates generated from both anilines and diazomalonates. The photochem. of anilines could be extended to other N-heterocycles, such as indole and carbazole. The reaction pathway for the selective C-C coupling was validated by electrochem. and photophys. experiments as well as computational studies.

The IL (ionic liquid) 1-(2-methoxyethyl)-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide [MOEMIM][NTf2] was prepared and confirmed by 1H NMR (1H NMR) spectroscopy and 13C NMR (13C NMR) spectroscopy. The d. and surface tension for the binary mixtures of [MOEMIM][NTf2] with methanol and ethanol were measured across the entire range of mole fraction (x1 = 0.0000-1.0000) at T = (288.15-318.15) K. The average molar volumes of the binary mixtures were calculated from the exptl. d., which increased with the increase of mole fraction and temperature The excess molar volumes, VEm, were obtained and fitted by Redlich-Kister equation. The interaction between ionic liquid and alc. is the strongest efficient packing and/or attractive interaction at the min. point. The lower the temperature was, the smaller the absolute value of excess molar volume was. The new function – the molar surface quasi-Gibbs energy of mixtures was obtained by us in this work. On a basis of molar surface quasi-Gibbs energy of mixtures, a new Eotvos equation was obtained of mixtures and applied to binary mixtures of [MOEMIM][NTf2] with alcs. The absolute value of the slope of the new Eotvos equation is the mole surface entropy, s, and the intercept is the molar surface enthalpy, h, which is temperature-independent. The deviation of molar surface quasi-Gibbs energy, Δgs, of mixtures for [MOEMIM][NTf2] with methanol and ethanol were calculated Δgs was well fitted by Redlich-Kister equation. In terms of Redlich-Kisters parameters, Ai, a new method for estimating the surface tension, γ, with any component of the mixtures is proposed and the estimated values, γ (estimate), are in good agreement with the corresponding exptl. ones, γ(exp.).

A method for the direct methylation of aryl, heteroaryl, and vinyl boronate esters is reported, involving the reaction of iodomethane with aryl-, heteroaryl-, and vinylboronate esters catalyzed by palladium and PtBu2Me. This transformation occurs with a remarkably broad scope and is suitable for late-stage derivatization of biol. active compounds via the boronate esters. The unique capabilities of this method are demonstrated by combining carbon-boron bond-forming reactions with palladium-catalyzed methylation in a tandem transformation.

An unprecedented N-demethylation of N-Me amides has been developed by use of N-fluorobenzenesulfonimide as an oxidant with the aid of a copper catalyst. The conversion of amides to carbinolamines involves successive single-electron transfer, hydrogen-atom transfer, and hydrolysis, and is accompanied by formation of N-(phenylsulfonyl)benzenesulfonamide. Carbinolamines spontaneously decompose to N-demethylated amides and formaldehyde, because of their inherent instability.

A series of simple donor-acceptor mols. consisting of an oligo-oxyethylene (OOE) N-substituted diphenylamine connected to a dicyanovinyl (DCV) acceptor group by a thienyl π-conjugating spacer are synthesized. Amorphous deep-red freshly cast thin films rapidly evolve towards an almost colorless pale beige poly-crystalline stable material from which a deep-red photoluminescent state can be switched-on by mech. stimulation. The effects of the length of the OOE chain on the mol. packing of the material and on the dynamics of the recovery process and aggregation in solution are analyzed. Crystallog. results show that the length of the OOE chain directly controls the mol. packing from head-to-tail arrangement of the dipoles for short chain to co-facial dimers leading to a non-centrosym. material with nonlinear optics (NLO) activity for the longer ones. The anal. of the dynamics of the self-recovery process of thin films and of mol. aggregation in solution shows that the dynamics of both processes is directly controlled by the length of the OOE chain. Since, as confirmed by optical and electrochem. results, the OOE substituents have strictly no influence on the electronic properties of the π-conjugated system, the observed effects are unambiguously related to changes in intermol. interactions.

Aryl ether formation is accomplished by oxidative condensation of alcs. and 2-cyclohexenones. The reaction complements the existing methods used by synthetic chemists to obtain aryl ethers, and allows a straightforward access to a wide range of functionalized products. In addition, the catalytic reaction with O2 as the oxidant generates water as the only byproduct and provides a “”greener”” approach to aryl ethers.
