Dakarapu, Rambabu; Falck, John R. published the artcile< Stereospecific Stille Cross-Couplings Using Mn(II)Cl2>, Application In Synthesis of 887266-99-1, the main research area is manganese chloride stereoselective Stille cross coupling reaction catalyst; organotin aryl iodide stereoselective Stille coupling reaction.

Cross-coupling reactions are a staple in organic synthesis, especially for C-C bond formation with sp- and sp2-carbon electrophiles. In recent years, the range of accessible C-C bonds has been extended to stereogenic centers which expedites access to greater mol. complexity. However, these reactions predominantly depend upon late transition metal (LTM) catalysts whose cost, toxicity, and/or environmental impact have come under increasing scrutiny and governmental regulation. Here, we report Mn(II)Cl2 complexes alone, or with assistance from copper, catalyze the stereospecific cross-coupling of α-alkoxyalkylstannanes with organic electrophiles with complete retention of configuration.

Wang, Hao-Yang; Gao, Ying; Zhang, Fang; Yu, Chong-Tian; Xu, Chu; Guo, Yin-Long published the artcile< Mass Spectrometric Study of the Gas-Phase Difluorocarbene Expulsion of Polyfluorophenyl Cations via F-Atom Migration>, Name: 1,4-Difluoro-2-iodobenzene, the main research area is mass spectrometry polyfluorophenyl cation gas phase difluorocarbene expulsion; fluorine atom migration.

An increasing number of fluorinated drugs, pesticides, and fine chems. are now produced and applied, especially those containing polyfluorinated aromatic moieties. However, at present, the extent of literature covering the special mass spectrometric behaviors of these compounds remains limited. Herein, we report an unexpected but also general gas-phase dissociation mode of polyfluorinated aromatics in mass spectrometry: expulsion of difluorocarbene (50-Da neutral loss). Results from accurate mass measurements, tandem mass spectrometric experiments, and d. functional theory (DFT) calculations support an intramol. F-atom “”ring-walk”” migration mechanism for gas-phase CF2 loss. Based on an assessment of the electron ionization-mass spectrometry (EI-MS) data of more than 40 polyfluorinated aromatic compounds from the National Institute of Standards and Technol. data bank, we generalized on the substitution group effects on the difluorocarbene dissociation process of polyfluorinated aromatic compounds in EI-MS. These studies have enriched our knowledge of the special gas-phase reactivity of polyfluorinated aromatics and will provide valuable information in further anal. research of these compounds by mass spectrometry.

An efficient cesium carbonate-mediated synthesis of phenothiazine derivatives from S-2-acetamidophenyl ethanethioates and ortho-dihaloarenes has been developed. This protocol affords an efficient approach for the construction of phenothiazine derivatives without the need of transition-metal catalyst or ligand. A plausible mechanism is proposed.

Gao, Yuan; Sachinthani, K. A. Niradha; Zheng, Chao; Jarrett-Wilkins, Charlie; Johnston, Andrew; Sun, Meng-Jia; Najarian, Amin Morteza; Wang, Ya-Kun; Saidaminov, Makhsud I.; de Arquer, F. Pelayo Garcia; Seferos, Dwight S.; Hoogland, Sjoerd; Sargent, Edward H. published the artcile< Self-Aligned Non-Centrosymmetric Conjugated Molecules Enable Electro-Optic Perovskites>, Safety of 3-Fluoro-4-iodobenzonitrile, the main research area is self aligned non centrosym conjugated mol electro optic perovskite.

Solution-processed organic electro-optic (EO) chromophores are well suited for integration in optical modulators on silicon photonics chips. They contain highly conjugated mols. with polar functional groups offering large dipoles and a large nonlinear optical response. However, these mols. form centrosym. aggregates that hinder poling efficiency and the resultant macroscopic EO response. Furthermore, at elevated temperatures, the alignment of poled mols. can be lost, leading to a reduction in the EO response. Inorganic EO materials exhibit excellent thermal stability but lower performance. Here 2D metal halide perovskite scaffolds that align EO mols. are reported. The approach heralds a material design strategy that combines the features of organic and inorganic EO materials. The EO material exhibits promising thermal stability with a performance approaching that of organic EO materials. Anchor diammonium non-centrosym. mols. are anchored inside a 2D metal halide perovskite scaffold, thereby avoiding aggregation. The authors lever the thermal stability of this compound and pole the organic mols. under an elec. field at 533 K. The 2D perovskites exhibit a macroscopic EO coefficient of 68 pm V-1-a twofold increase over LiNbO3. D. functional theory calculations show that the in-plane alignment of the mol. dipole moments can account for the EO response.

Yang, Peng-Fei; Zhu, Lei; Liang, Jian-Xing; Zhao, Han-Tong; Zhang, Jian-Xin; Zeng, Xian-Wang; Ouyang, Qin; Shu, Wei published the artcile< Regio- and Enantioselective Hydroalkylations of Unactivated Olefins Enabled by Nickel Catalysis: Reaction Development and Mechanistic Insights>, SDS of cas: 167479-01-8, the main research area is mechanism hydroalkylation olefin alkyl halide regioselective enantioselective nickel catalyst; alkene alkyl halide nickel catalyst enantioselective regioselective hydroalkylation; alkyl amide preparation.

Direct construction of fully alkyl-substituted tertiary chiral centers remote to activating groups is highly challenging and desirable. Herein, a Ni-catalyzed enantioselective hydroalkylation of unactivated alkenes with unactivated alkyl halides at room temperature is reported, providing a general and practical access to fully alkyl-substituted tertiary stereogenic carbon centers not adjacent to activating groups. This reaction undergoes regio- and stereoselective hydrometalation of unactivated alkenes with a nontrivial Markovnikov selectivity, followed by cross-coupling with unactivated alkyl electrophiles to access trialkyl tertiary saturated stereogenic centers not adjacent to activating groups. The mild and robust conditions enable the use of terminal and internal unactivated alkenes and unactivated primary and secondary alkyl, benzyl and propargyl halides to construct diverse trialkyl tertiary stereogenic carbon centers with broad functional group tolerance. Moreover, exptl. investigations support the reaction undergoing irreversible and stereoselective hydrometalation of alkenes. D. functional theory calculations provide further insights into the reaction mechanism, suggesting a stereoselective migration insertion of alkenes with Ni(II)-H species. Finally, the origin of the regio- and enantioselectivities was also investigated.

Boyle, Benjamin T.; Koniarczyk, J. Luke; McNally, Andrew published the artcile< Facile Pyridine SNAr Reactions via N-Phosphonium-Pyridinium Intermediates>, Safety of 4-Iodopyridin-3-ol, the main research area is pyridine nucleophilic aromatic substitution reaction halopyridine phosphine; phosphonium pyridinium intermediate; SNAr reaction; phosphonium salts; pyridines; pyridinium salts.

Here we report that N-phosphonium pyridinium intermediates are unusually reactive for pyridine SNAr reactions. Specifically, forming phosphonium salts from halopyridines typically requires elevated temperatures and Lewis acid additives. The alternative activation mode described in this paper permits C-P bond formation to occur at ambient temperatures in many cases, and functions across a broad range of substrates.
