A straightforward synthesis of indazolo[3,2-a]isoquinolin-6-amines [PDF]
, 2013 4-Substituted 1-bromoisoquinolin-3-amines were subjected to Suzuki coupling with o-nitrophenylboronic acid to yield 1-(2-nitrophenyl) isoquinolinamines, which participated in Cadogan cyclization with triethyl phosphite under microwave irradiation in a ...

Advanced Science, EarlyView.A visible‐light‐mediated method has been developed for the direct conversion of biomass into formate at ambient temperature and atmospheric pressure. This approach achieves the selective generation of hydroxyl radicals, which subsequently transform sugars, cellulose, and hemicellulose into formate.

3-(9H-Carbazol-9-yl)-2H-chromen-2-one [PDF]
, 2011 The title compound, C21H13NO2, was prepared as an example of a new synthesis of carbazoles from a cyclic dibenzo-iodolium salt via a twofold Pd-catalysed arylation of a primary amine. The two essentially planar π-subsystems [maximum deviations from the

Advanced Science, EarlyView.Conjugated microporous polymer membranes with narrowly distributed network pores are prepared by diffusion‐modulated electropolymerization. This approach precisely controls the monomer diffusion and coupling processes, regulating the crosslinking degree to prevent broad aggregate pores and microporous defects.

First-principles study of Carbz-PAHTDDT dye sensitizer and two Carbz-derived dyes for dye sensitized solar cells [PDF]
arXiv, 2014 Two new carbazole-based organic dye sensitizers are designed and investigated in silico. These dyes are designed through chemical modifications of the conjugated bridge of a reference organic sensitizer known as Carbz-PAHTDDT (S9) dye. The aim of designing these dyes was to reduce the energy gap between their highest occupied molecular orbital (HOMO ...

Synthesis of N-acyl carbazoles, phenoxazines and acridines from cyclic diaryliodonium salts
Beilstein Journal of Organic ChemistryN-Acyl carbazoles can be efficiently produced through a single-step process using amides and cyclic diaryliodonium triflates. This convenient reaction is facilitated by copper iodide in p-xylene, using the commonly found activating ligand diglyme.
