3,6-Dibromo-9-(4-bromobenzyl)-9H-carbazole

Acta Crystallographica Section E, 2009
The title compound, C19H12Br3N, was synthesized by N-alkylation of 1-bromo-4-(bromomethyl)benzene with 3,6-dibromo-9H-carbazole. There are two unique molecules in the asymmetric unit. The carbazole ring system is essentially planar, with a mean deviation

Tailoring Amine Substitution in Fluorene and Dibenzothiophene: A Molecular Strategy for Ultralong Organic Phosphorescence

Advanced Optical Materials, EarlyView.
Tailored amine substitution in fluorene and dibenzothiophene derivatives enables systematic control of excited‐state properties and triplet population. Combined photophysical studies, TD‐DFT calculations and time‐resolved EPR reveal how charge‐transfer character, sulfur‐induced spin–orbit coupling and triplet manifold engineering cooperate to promote ...

Benzene as a by-product of toluene with methanol transformation on the basic zeolite catalysts and its presumable origin

Adsorption Science & Technology, 2017
The goal of the present study was to clarify the nature of benzene forming in base catalyzed side-chain alkylation of toluene with methanol. Benzene formation has been observed as a primary product in the very beginning of conversion of toluene/methanol ...

9-Benzyl-3-bromo-9H-carbazole

Acta Crystallographica Section E, 2009
The title compound, C19H14BrN, was synthesized by the N-alkylation of (chloromethyl)benzene with 3-bromo-9H-carbazole. The carbazole ring system is essentially planar (r.m.s. deviation = 0.013 Å) and forms a dihedral angle of 87.1&#

New catalytic strategies for DNA and RNA alkylation using rhodium (II) and copper (I) carbenes - a versatile tool for applications in chemical biology [PDF]

, 2015
A variety of nucleic acid substrates were catalytically alkylated with rhodium(II) and copper(I)-carbenoids generated from diazocarbonyl compounds. The alkylation took place via an N-H insertion reaction selectively targeting the nucleobases in single ...
