Wang, Yajie published the artcileAn Air-Stable N-Heterocyclic [PSiP] Pincer Iron Hydride and an Analogous Nitrogen Iron Hydride: Synthesis and Catalytic Dehydration of Primary Amides to Nitriles, Computed Properties of 100-70-9, the main research area is iron nitrogen heterocyclic pincer hydride catalyst dehydration primary amide; nitrile preparation.

An air-stable N-heterocyclic PSiP pincer iron hydride FeH(PMe3)2(SiPh(NCH2PPh2)2C6H4) was synthesized by Si-H activation of a Ph-substituted [PSiP] pincer ligand. The analogous strong electron-donating iPr-substituted [PSiP] pincer ligand was prepared and introduced into iron complex to give an iron nitrogen complex FeH(N2)(PMe3)(SiPh(NCH2PiPr2)2C6H4). Both complexes showed similar high efficiency for catalytic dehydration of primary amides to nitriles. Air-stable iron hydride FeH(PMe3)2(SiPh(NCH2PPh2)2C6H4) was the best catalyst for its stabilization and convenient preparation A diverse range of cyano compounds including aromatic and aliphatic species was obtained in moderate to excellent yields. A plausible catalytic reaction mechanism was proposed.

Wang, Tengfei published the artcileExploration of catalytic species for highly efficient preparation of quinazoline-2,4(1H,3H)-diones by succinimide-based ionic liquids under atmospheric pressure: Combination of experimental and theoretical study, HPLC of Formula: 1885-29-6, the main research area is quinazoline carbon dioxide absorption ionic liquid catalyst.

Cyclization reaction of carbon dioxide (CO2) and 2-aminobenzonitriles is of significance for the sustainable development, however, the harsh reaction condition especially for the high CO2 pressure is still an obstacle. Herein, a novel ionic liquid benzyltrimethylammonium succinimide ([BzTMA+][Suc-]) is designed and synthesized, in which no active hydrogen atom is included in cation. It displays the excellent catalytic activity achieving the 98.8% yield for quinazoline-2,4(1H,3H)-diones even under the atm. pressure. By combination of NMR spectroscopy (1H NMR and 13C NMR), CO2 absorption measurements, d. functional theory (DFT) calculations, and the frontier MO anal., the real catalytic species and synergistic effect of cation and anion on the catalytic performance are elucidated. The [Suc-] anion affords to introduce the CO2 into the organic phase even under the atm. pressure by formation of [Suc-CO-2]. However, the real catalytic species is [BzTMA+] cation and [Suc-] anion rather than [BzTMA+] and [Suc-CO-2]. If the active hydrogen atom is included in the cation, the CO2 absorption capacity of [Suc-] anion would be weakened by the strong interaction between active hydrogen atom in cation and [Suc-] anion resulting in the inferior catalytic behavior. The cooperation of [BzTMA+] and [Suc-] finally results in the high catalytic activity under the atm. pressure. Involvement of active hydrogen atom in cation is not an insurance to prepare the robust catalyst.

Betori, Rick C. published the artcileReductive Arylation of Arylidene Malonates Using Photoredox Catalysis, Application In Synthesis of 100-70-9, the main research area is diaryl malonate preparation; arylidene malonate reductive arylation photoredox catalysis.

A strategy with arylidene malonates provides access to β-umpolung single-electron species. Reported here is the utilization of these operators in intermol. radical-radical arylations, while avoiding conjugate addition/dimerization reactivity that is commonly encountered in enone-based photoredox chem. This reactivity relies on tertiary amines that serve to both activate the arylidene malonate for single-electron reduction by a proton-coupled electron transfer mechanism as well as serve as a terminal reductant. This photoredox catalysis pathway demonstrates the versatility of stabilized radicals for unique bond-forming reactions.

Ghadermazi, Mohammad published the artcileIntroduction of Fe into mesoporous MCM-41 for the synthesis of 5-substituted 1H-Tetrazoles from aryl nitriles in water, Related Products of nitriles-buliding-blocks, the main research area is mesoporous supported iron silica catalyst preparation; tetrazole sulfoxide preparation green chem; aryl nitrile sulfide oxidation water.

In this exploration, new recyclable mesoporous-supported iron particles with the ligand and without ligand (MCM-41@ 3,4,5-tri hydroxyphenyl acetic acid @Fe and MCM-41@Fe) have been developed through post-functionalization modification of silica MCM-41. These catalysts were demonstrated to be novel, effective, and green for the synthesis of 5-substituted 1H-tetrazoles from aryl nitriles in water. In these systems, 5-substituted 1H-tetrazoles are produced as the only product. Fe3+ species were identified as active sites. The ordered mesoporous iron-silica catalyst with the ligand displayed better catalytic activity compared to iron-silica catalyst without the ligand, which was ascribed to the improvement of the inter-action of iron with the support. The catalysts can be easily separated using simple recovery and reused several times with consistent activity.
