Novel 2-amino-isoflavones exhibit aryl hydrocarbon receptor agonist or antagonist activity in a species/cell-specific context [PDF]

, 2012
The aryl hydrocarbon receptor (AhR) mediates the induction of a variety of xenobiotic metabolism genes. Activation of the AhR occurs through binding to a group of structurally diverse compounds, most notably dioxins, which are exogenous ligands ...

Photochemical Behaviour of Carbamates Structurally Related to Herbicides in Aqueous Media: Nucleophilic Solvent Trapping versus Radical Reactions

International Journal of Photoenergy, 2014
Irradiation of N-aryl O-aryl carbamates has been carried out in H2O/CH3CN (1 : 1 v/v) solutions at λ>290 nm. When chlorine is on the N-aryl ring, halogen-substituted products are found.

Synthesis of 3-(4-(Benzo[d]thiazol-2-yl)phenyl)-5-aryl-1,3,5-oxadiazinane-4-thiones and 1-(4-(Benzo[d]thiazol-2-yl)phenyl)-5-methyl-3-aryl-1,3,5-triazinane-2-thiones

SynOpen, 2018
In this investigation 4-(benzo[d]thiazol-2-yl)benzenamine was reacted with aryl isothiocyanates to give 1-(4-(benzo[d]thiazol-2-yl)phenyl)-3-aryl thioureas 2, which were cyclized with acid to afford 3-(4-(benzo[d]thiazol-2-yl)phenyl)-5-aryl-1,3,5 ...

para-Selective C-H amidation of simple arenes with nitriles [PDF]

, 2015
A para-selective C-H amidation of simple arenes with nitriles has been developed. By increasing the amount of arenes, a further meta-selective C-H arylation of the produced amides occurred.

Iodine-Mediated Facile One-Pot Access to N-Aryl-2-benzoxazolamines

SynOpen, 2020
Facile, iodine-mediated access to N-aryl-2-benzoxazolamines has been achieved in a one-pot manner under mild reaction conditions. Reaction of 2-aminophenols and aryl isothiocyanates afforded N-aryl-2-benzoxazolamines in the presence of molecular iodine ...

The Electrochemical Oxidation of Organic Selenides and Selenoxides [PDF]

, 1997
The electrochemical oxidation of alkyl and aryl selenides was investigated in acetonitrile. The oxidation of diphenyl selenide and di(4‐methylphenyl) selenide led primarily to the formation of their respective selenoxides, which were identified by ...
