Aryl phosphonates are functional groups frequently found in pharmaceutical and crop protection agents. For their synthesis via C?P bond formation typically transition-metal-catalyzed reactions are used. We report a visible-light photo-Arbuzov reaction as an efficient, mild, and metal-free alternative. Rhodamine 6G (Rh.6G) is used as the photocatalyst, generating aryl radicals under blue light. Coupling of the radicals with a wide range of trivalent phosphites gives aryl phosphonates in good to very good isolated yields. The mild reaction conditions allow the introduction of a phosphonate group into complex and sensitive pharmaceutically active molecules such as benzodiazepams and nicergoline by the activation of a carbon?halogen bond.

Thienylzinc halides and related compounds prepared by deprotonation followed by transmetalation were used in copper-catalyzed amination using N-benzoyloxy secondary amines. By extending the reaction to 1,5-naphthyridine, it was showed that the competitive dimer formation observed in the case of thiophenes was linked with the low stability of some thienylamines rather than homocoupling. Interestingly, thienylzinc halides and related compounds prepared by transmetalation of thienylmagnesium halides, either prepared from their bromo-precursors or generated by deprotometalation, were satisfactorily employed in cobalt-catalyzed aminations. Finally, aminothiophenes were involved in copper-catalyzed mono- and di-N-arylations, affording differently substituted di- and triphenylamines.

Medicinally relevant diarylamines are prepared through a photoredox-mediated dual catalytic nickel/ruthenium system from aryl azides and aryl electrophiles. Photoreduction of the aryl azide is proposed to proceed through an arylnickel-azide complex, which upon reduction and loss of nitrogen, generates a nickel(III) species capable of facile reductive elimination to afford the desired C-N bond formation. A variety of functionalized (hetero)aryl electrophiles are shown to participate in the coupling, including iodides, bromides, chlorides, and triflates. The reactions are simple to set up and are performed under ambient conditions, without the exclusion of oxygen or moisture.

“Figure Presented” We describe the coupling of primary sulfonamides and various halogenated heterocyclic cores, with an emphasis on 2-heteroaryl halides, via copper catalysis. These studies enabled the synthesis of many new mono-N-heteroaryl sulfonamides. The electronic factors that influence the course of the reaction have also been investigated.

A series of Pd(II)-enaminone complexes, termed Pd(eao)2, have been synthesized and characterized. The investigation on the catalytic activities of these new Pd(II)-reagents has proved that the Pd(eao)2-1 possesses excellent catalytic activity for the Suzuki- Miyaura cross coupling reactions of aryl bromides/chlorides with aryl/vinyl boronic acids in the environmentally benign media of aqueous PEG400 at low loading (5 mol?). The superiority of this Pd(II)-reagent to those commercial Pd(II) and Pd(0) catalysts in catalyzing the reactions has been confirmed by parallel experiments. What’s more, Pd(eao)2-2 has been found as a practical catalyst for the homo-coupling reactions of aryl boronic acids.

Synthetic Route of 2516-40-7, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.2516-40-7, Name is 2-Bromobenzothiazole, molecular formula is C7H4BrNS. In a patent, introducing its new discovery.

N?C?N cyclometalated iridium(III) acetylide complexes in the 3 + 2+1 ligand mode were obtained and characterized. Cyclometalating ligands were bis(pyridyl)phenyl, bis(benzothiazolyl)phenyl and 2-phenylpyridine derivatives, while acetylene ligands represented 2-ethynylfluorene and 3-ethynylcarbazole derivatives. The HOMOs of the ethynyl iridium complexes are located on the ethynyl ligand and the iridium atom, whereas the LUMO is located exclusively on the N?C?N-cyclometalating ligand. All compounds showed phosphorescent properties, where the change of ligands significantly affects the wavelength of emission. Acetylide complexes emit light from the blue (? 400 nm) to orange (? 560 nm) range. Emission occurs from the mixed state 3MLCT/3LC, with a predominance of junction depending on the structure of the ligands.

Herein we report a highly efficient method for nickel-catalyzed C?N bond formation between sulfonamides and aryl electrophiles. This technology provides generic access to a broad range of N-aryl and N-heteroaryl sulfonamide motifs, which are widely represented in drug discovery. Initial mechanistic studies suggest an energy-transfer mechanism wherein C?N bond reductive elimination occurs from a triplet excited NiII complex. Late-stage sulfonamidation in the synthesis of a pharmacologically relevant structure is also demonstrated.
