The behavior in solution and in the solid state of 3(5)-phenyl-1H-pyrazole (7), 3(5)-phenyl-4-chloro-1H-pyrazole (6), 3(5)-phenyl-4-bromo-1H-pyrazole (1), and 3(5)-p-chlorophenyl-4-bromo-1H-pyrazole (8) is discussed in relation to their 3-phenyl (a)/5-phe

The estimated excited oxidation potential of sodium anthraquinone-2-sulfonate (SAS) increases from 1.8 V to about 2.3 V vs SCE by protonation with Br?nsted acids. This increased photooxidation power of protonated anthraquinone was used for the regio-selective oxidative bromination of electron rich (hetero)arenes and drugs in good yield. The mild reaction conditions are compatible with many functional groups, such as double and triple bonds, ketones, amides and amines, hydroxyl groups, carboxylic acids and carbamates. Mechanistic investigations indicate the photooxidation of the arene followed by nucleophilic bromide addition as the likely pathway. (Figure presented.).

While the p90 ribosomal S6 kinase (RSK) family has been implicated in multiple tumor cell functions, the full understanding of this kinase family has been restricted by the lack of highly selective inhibitors. A bis-phenol pyrazole was identified from hig
