Photocatalytic Functionalization of Dihydroquinoxalin‐2‐Ones with Pyrazolones
نویسندگان
چکیده
A visible-light photoredox functionalization of 3,4-dihydro-quinoxalin-2-ones with pyrazolones using an inexpensive organophotoredox catalyst is described. The reaction uses 9,10-phenanthrenedione as photocatalyst, a very simple and cheap HP single Blue LED (455 nm) source oxygen from air terminal oxidant, obtaining the corresponding acetylated pyrazoles good yields. can be extended to other nitrogen heterocycles such 5-aminopyrazoles results

Hypersensitivity to pyrazolones.
To the allergologist, hypersensitivity to drugs means immunological drug reactions as classified in the Gell and Coombs system. To others, it may also include non-dose related adverse drug reactions including the non-immune mediated idiosyncratic drug reactions (type B). In the following discussion the broad definition of idiosyncrasy including all type B reactions and a clinical approach rathe...
متن کاملFunctionalization of Carboxylated Multi-Walled Nanotubes with Stabilised Phosphorus Ylide
In this paper, the chemical Functionalization of Carboxylate multi-walled carbon nanotubes by methyl (triphenyl phosphoranylidene) acetate have been investigated. Phosphorus Ylides are important compound in organic chemistry. At first, methyl (triphenyl phosphoranylidene) acetate, synthesized from salt metod in two steps: the formation of the phosphonium salt and the deprotonation of the latter...
متن کاملAn easy direct arylation of 5-pyrazolones
A mild, efficient and catalytic ligand-free method for the direct arylation of 5-pyrazolones by Pd-catalyzed C-H bond activation is reported. The process smoothly proceeds and yields are moderate to excellent.
متن کاملFunctionalization of Carboxylated Multi-wall Nanotubes with 1,2-phenylenediamine
In this paper, the chemical functionalization of carboxylated multi-walled carbon nanotubes (MWNT-COOH) by 1,2-phenylenediamine, have been investigated. MWNT-benzimidazole is obtained through MWNT-Amide reaction with POCl3 after 72h, which is confirmed by FT-IR, SEM, TGA, and elemental analysis. These functionalizations have been chosen due to NH2 and NHCO active sites in MWNT-Amide for future...
