Experimental and Computational Study of the 1,5-O -> N Carbamoyl Snieckus-Fries-Type Rearrangement

The reactions of o-lithiated O-aryl N,N-diethylcarbamates with different C-N multiple bond electrophiles have been thoroughly studied. A 1,5-O -> N carbamoyl shift, a new variation of the anionic Fries-type rearrangement, takes place when nitriles, imines, or alkylcarbodiimides are employed. In these cases, the carbamoyl group plays a dual role as a directing group, building up a variety of functional groups through the 1,5-O -> N carbamoyl migration. On the other hand, the use of iso(thio)cyanates and arylcarbodiimides led to non-rearranged o-functionalized O-arylcarbamates. This reactivity was further computationally explored, and the governing factor could be traced back to the relative basicity of the alternative products (migrated vs nonmigrated substrates). This exploration also provided interesting insights about the degree of complexation of the lithium cations onto these substrates. A new access to useful 2-hydroxybenzophenone derivatives has also been developed.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 67604-48-2 is helpful to your research. Product Details of 67604-48-2.

Interfacial electronic interaction of atomically dispersed IrClx on ultrathin Co(OH)(2)/CNTs for efficient electrocatalytic water oxidation

The exploration of highly-efficient oxygen evolution reaction (OER) electrocatalyst with well-defined structure to understand specific structure-performance relationship is crucial to meet the requirement of water-splitting. Herein, we firstly used atomically dispersed IrClx to uniformly decorate ultrathin Co(OH)(2) nanosheets to dramatically improve electrocatalytic activity. The synthesized IrClx-Co(OH)(2) nanosheets/carbon nanotubes (CNTs) exhibits an overpotential of 230 mV to reach 10 mA/cm(2), which was much enhanced compared to that of pristine Co(OH)(2)/CNTs (308 mV) and commercial benchmark IrO2(309 mV). X-ray absorption fine structure and density functional theory simulations demonstrate strong interfacial interaction between IrClx and Co(OH)(2) nanosheets via the Cl-Ir-O and Ir-Cl-Co bond can efficiently boost its electronic conductivity. The accelerated charge transfer promotes the formation of more positively charged O atoms around cobalt centers, which is beneficial for the deprotonation on IrClx-Co(OH)(2) and makes the catalyst facilitate OER.

Preparation and physical properties of intrinsic low-k polyarylene ether nitrile with enhanced thermo-stability

Polyarylene ether nitrile (PEN) random copolymers were prepared from 6AF, BHPF, and 2, 6-dichlorobenzonitrile according to the nucleophilic aromatic substitution polymerization. The chemical structure of PEN random copolymers was characterized by the FT-IR and H-1-NMR spectrum, respectively. The thermal properties of the PEN random copolymers were investigated by using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The resulting PEN copolymers have excellent thermal stability with high glass transition temperature (T-g) ranging from 187? to 271? and the 5% weight loss temperature (T-5%) of PEN copolymers greater than 490? in nitrogen atmospheres. Meanwhile, the PEN films have excellent mechanical property, the tensile strength ranges from 55 to 95 MPa. Moreover, the dielectric properties of the PEN random copolymers were investigated by dielectric tests. The dielectric constants (k) and loss tangent (tan delta) of PEN (PEN-6-AF/BHPF100) film is only 2.3 and 0.03 at 1 kHz, respectively. More importantly, the dielectric properties were found to be relatively stable until the T-g, which can be attributed to the existence of BHPF units in the molecular backbone.

Palladium(ii)-catalyzed three-component tandem reactions: synthesis of multiply substituted quinolines

The three-component tandem reaction of 2-aminobenzonitriles, arylboronic acids and ketones allowing the synthesis of polysubstitution quinolines is reported. This strategy presents a practical, efficient, one-pot procedure that delivers functional quinolines in moderate to good yields with high functional group tolerance. To enrich the synthetic applications in accessing diverse quinolines, a new method for the introduction of halogen substituents into target products has been developed as well, which shows potential for further synthetic elaborations.

Suzuki-Miyaura Arylations of Tetramic Acid Sulfonates: Evaluation of Lactam Protection, Sulfonate Esters, and Sterics

The synthesis of 3,4-diaryl-3-pyrroline-2-ones and 4-aryl-3-pyrrolin-2-ones using Suzuki-Miyaura cross-coupling reactions of tetramic acid sulfonates with arylboronic acids has been studied. The effect that sulfonate ester, sterics, and lactam protection has on the cross-coupling reaction was evaluated. As expected, triflates were better cross-coupling partners than the corresponding tosylates. The yields were only partially affected by the incorporation of aryl groups at the 3-position. Importantly, tetramic acid triflates (and to a lesser extent tosylates) lacking a lactam protecting group were still competent substrates.
