Ditopic binding of various dinitrogen compounds to three bisporphyrin molecular tweezers with spacers of varying conformational rigidity, incorporating the planar enediyne (1), the helical stiff stilbene (2), or the semi-rigid glycoluril motif fused to the porphyrins (3), are compared. Binding constants Ka = 104-106 M-1 reveal subtle differences between these tweezers, that are discussed in terms of porphyrin dislocation modes. Exciton coupled circular dichroism (ECCD) of complexes with chiral dinitrogen guests provides experimental evidence for the conformational properties of the tweezers. The results are further supported and rationalized by conformational analysis.

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 109073-77-0, molcular formula is C12H12N2O2, introducing its new discovery.

Force-reactivity property of a single monomer is sufficient to predict the micromechanical behavior of its polymer

We demonstrate an accurate prediction of the micromechanical behavior of a single chain of cyclopropanated polybutadiene, which is governed by rapid isomerization of the cyclopropane moieties at ?1.2 nN, from the force-rate correlation of this reaction measured in a small series of increasingly strained macrocycles. The data demonstrate that a single physical quantity, force, uniquely defines the dynamics across length scales from >100 to <1 nm and that strain imposed through molecular design and that imposed by micromanipulation techniques have equivalent effects on the kinetics of a chemical reaction. This represents a new method of screening potential monomers for applications in stress-responsive materials that could also facilitate atomistic interpretations of single-molecule force experiments.

Two-carbon ring expansion of 1-indanones via insertion of ethylene into carbon-carbon bonds

A rhodium-catalyzed direct insertion of ethylene into a relatively unstrained carbon-carbon bond in 1-indanones is reported, which provides a two-carbon ring expansion strategy for preparing seven-membered cyclic ketones. As many 1-indanones are commercially available and ethylene is inexpensive, this strategy simplifies synthesis of benzocycloheptenones that are valuable synthetic intermediates for bioactive compounds but challenging to prepare otherwise. In addition, the reaction is byproduct-free, redox neutral, and tolerant of a wide range of functional groups, which may have implications on unconventional strategic bond disconnections for preparing complex cyclic molecules.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.109073-77-0,[2,2′-Bipyridine]-4,4′-diyldimethanol,as a common compound, the synthetic route is as follows.

This reaction was performed under nitrogen atmosphere using freshly distilled,anhydrous solvents and reagents. Thionyl chloride (1.02 mL,14.0 mmol) was diluted with CH2Cl2 (15 mL) and the solution,cooled to 0 C, was added dropwise via syringe over 2 min to a cold(0 C) solution of lipoic acid (1.94 g, 9.36 mmol) in CH2Cl2 (25 mL).The solution was stirred at 0 C for 1 h, then the ice bath was removedand the solution was allowed to reach room temperature over 1 h. The solvents were removed in vacuo to leave lipoylchloride as a pale brown residue. This was dissolved in toluene (25 mL) and added dropwise over 30 min to a flask charged witha cold (0 C) solution of 3 (200 mg, 0.936 mmol) and Et3N (4.50 mL)in toluene (20 mL). The reaction was stirred overnight. Water(75 mL) was added, resulting in the formation of a brown precipitate.The mixture was filtered, the solid was discarded, and the organic layer was washed with water (250 mL) and dried over anhydrous Na2SO4. The solvent was removed in vacuo, to obtaina yellow crude product. This was purified by column chromatography using neutral alumina and hexane/ethyl acetate (2:1). After the less polar fraction (mostly lipoic acid) was separated, the eluentwas changed to hexane/ethyl acetate (1:4) to collect the fractions with the product. The solvent was removed in vacuo and theproduct was obtained as a yellow solid, 109073-77-0
