An Expedient Synthesis of 5,11-Dimethylindolo[3,2-b]-carbazole, A Potent Ligand for the Receptor for TCDD
摘要:
A new and efficient synthesis has been developed for the title indolocarbazole which has been indicated by a recent computer-aided study to be a potent ligand for the receptor for the naturally occurring carcinogen, TCDD.
On Attempted Oxidative Cyclisation of Isomeric<i>N,N'</i>-Diphenylphenylenediamines and Their<i>N,N</i>'-Dimethyl Derivatives by Palladium(II) Acetate and Uv Light
Abstract The cyclisation of N,N'-diphenyl-o-, m- and p-phenylenediamines and their N,N'-dimethyl derivatives by palladium(II) acetate and UV light separately led to both bis-cyclisation, furnishing indolocarbazoles, and mono-cyclisations with cleavage as well as retention of one substituent, producing substituted carbazoles.

and applied to iodine capture. The An[2]s showed remarkable iodine uptake capacities of up to 7.35 g g−1 in the vapor phase and significantly fast adsorption kinetics in both vapor and aqueoussolutions. A new mechanism called reverse dissolution was proposed based on the unusually high iodine-loading capacities and the crystal-to-amorphous phase transition properties. The adsorbed iodine could be readily

palladium-catalyzed chemoselective amination of chloro(hetero)aryl triflates in the C−Cl bond for the first time. A newly designed and synthesized alkyl-pyrazole-based phosphine ligand, L26 (BirdPhos), which is featured with the pyrazole ligand core and the cyclohexyl group at the C3 and C5 positions, was key to the success of this reaction. A variety of chloro(hetero)aryl triflates coupled with aromatic, aliphatic
