Lang, Simon B. published the artcileActivation of Alcohols with Carbon Dioxide: Intermolecular Allylation of Weakly Acidic Pronucleophiles, COA of Formula: C16H13NO, the main research area is nitroalkane allyl alc carbon dioxide palladium allylation catalyst; nitrile allyl alc carbon dioxide palladium allylation catalyst; aldehyde allyl alc carbon dioxide palladium allylation catalyst; allylated product preparation.

The direct coupling of allyl alcs. with nitroalkanes, nitriles, and aldehydes using catalytic Pd(PPh3)4 has been accomplished via activation of C-OH bonds with CO2. The in situ formation of carbonates from alcs. and CO2 facilitates oxidative addition to Pd to form reactive π-allylpalladium intermediates. In addition, the formation of a strong base activates nucleophiles toward the reaction with the π-allylpalladium electrophile. Overall, this atom economical reaction provides a new C-C bond without the use of an external base and generates water as the only byproduct.

Abel-Snape, Xavier published the artcileSynthesis of Indenes and Benzofulvenes via a Palladium-Catalyzed Three-Component Reaction, Formula: C7H6N2, the main research area is indene benzofulvene preparation palladium catalyst three component reaction.

A palladium-catalyzed three-component domino reaction to access indene derivatives is reported. This reaction proceeds via the sequential formation of three bonds: the first two resulting from inter- and intramol. carbopalladation and the final bond arising from an attack by a terminating nucleophilic reagent. Modifying the starting tether on the iodoarene led to either indenes or benzofulvenes. Three termination variations were compatible with this sequence, which furnished products in moderate to good yields. The oxabicycle used in this work acts as an acetylene surrogate, which is revealed in a postcatalytic retro-Diels-Alder step. A diastereomerically enriched mixture of oxabicyclic derivatives allowed for preliminary results for the enantioselective synthesis of indenes.

Mohammadinezhad, Arezou published the artcileCoII immobilized on an aminated magnetic metal-organic framework catalyzed C-N and C-S bond forming reactions: a journey for the mild and efficient synthesis of arylamines and arylsulfides, HPLC of Formula: 1885-29-6, the main research area is arylamine preparation; amine aryl halide cross coupling cobalt nanocatalyst; arylsulfide preparation; aryl halide thiol cross coupling cobalt nanocatalyst.

A simple and versatile method for the modification of a metal-organic framework (NH2-MIL53(Al)) in a step-wise manner was reported. To characterize the synthesized nanostructured catalyst, a variety of spectroscopic and microscopic techniques including FT-IR, XRD, BET, TEM, FE-SEM, EDX, EDX-mapping, TGA, XPS, VSM, ICP-OES and CHN have been employed. Fe3O4@AMCA-MIL53(Al)-NH2-CoII NPs, which benefit from small nanocrystalline size (10-30 nm, according to the XRD and TEM data) in combination with the coexistence of magnetic nanoparticles, a metal-organic framework, and cobalt species, were found to be an excellent environment catalyst to promote the C-N and C-S cross coupling reactions. A wide range of functional substrates including electron-withdrawing and electron-donating aryl halides RC6H4X (R = H, 2-O2N, 3-H3C, 4-CHO, etc.; X = I, Br, Cl) underwent the coupling reaction with aromatic/heteroaromatic/benzylic and aliphatic amines R1NH2 (R1 = Bu, 2-pyridy, 2-chlorobenzyl, 4-bromophenyl, etc.) and sulfides R2NH2 (R2 = 3-sulfanylpropyl, 4-nitrophenyl, 2-hydroxyethyl, etc.). The results demonstrated that the yields of the target products RC6H4NHR1/RC6H4SHR2 were good to excellent and the catalyst can be recycled for at least seven recycling runs without a discernible decrease in its catalytic activity. Furthermore, the heterogeneity studies (such as hot filtration and poisoning tests) efficiently confirmed that the as-synthesized nanostructured catalyst is heterogeneous and completely stable under the reaction conditions. This study inspires more interest in designing novel catalysts based on using low-cost metal ions (such as cobalt) in the field of cross coupling reactions.

Zhou, Jingwei published the artcileCatalyst-free photoinduced selective oxidative C(sp3)-C(sp3) bond cleavage in arylamines, HPLC of Formula: 204078-32-0, the main research area is arylamine selective oxidative bond cleavage photochem catalyst free.

Due to the directional nature of sp3-hybridized orbitals and the absence of π-orbitals, the oxidative cleavage of the kinetically and thermodynamically stable C(sp3)-C(sp3) bond is extremely difficult and remains scarcely explored. In this work, under the double argument of quantum mechanics (QM) computations and meticulous experiments on authors’ well-designed C-C single bond cleavage mechanism, authors discovered a means of photoinduced selective oxidative C(sp3)-C(sp3) bond cleavage in arylamines, easily achieved by simple visible light irradiation using O2 as a benign oxidant under very mild conditions. The utility of methodol. was demonstrated by the C(sp3)-C(sp3) bond cleavage in morpholine/piperazine arylamines with excellent functional group tolerance. Importantly, this methodol. is noteworthy, not only it does not require any catalysts, but also it provides valuable possibilities for the scalable functionalization of clin. drugs and natural products.

The direct borylation of two bis(pyrazolylimino)isoindoline chelates with BF3 and base under dry conditions gave two B adducts. These are ring-contracted analogs of biliazine and can be considered as subbiliazines, as they have bowl-shaped structures similar to subphthalocyanine. Addnl., a new iminooxoisoindoline BF2 complex was made from hydrolysis of the free base in the presence of BF3. The electronic structures of the free bases and subbiliazines were probed by d. functional theory (DFT) and time-dependent DFT (TDDFT) methods.
