The selectivefluorination of compounds containing benzylic hydrogen atoms was accomplished by electrolysis in a mixture of 70% HF and 30% pyridine (Olah's reagent) using a square wave alternating current (1.76–2.75 V, 0.02–0.05 Hz) and Pt electrodes. This method can be used in the laboratory to prepare conveniently gram-size quantities of monofluorinated products. An ion radical mechanism has been
We describe a short, efficient approach for the synthesis of three novel isotopelabeled azobenzene photoswitches. The synthesis is based on commercially available fully isotopelabeled precursors. The target molecules have been obtained in good yields, checked for purity, and identified by NMR and IR spectroscopy and a variety of standard analytical methods (UV-vis, mp, ESI-MS, elemental analysis)

The present invention relates to isolated deuterated compounds (e.g., compounds described by Formula (I) and pharmaceutically acceptable salts thereof. The present invention also relates to isotopically enriched compositions that include compounds according to Formula (I) and pharmaceutically acceptable salts thereof. The invention also features pharmaceutical compositions that include these compounds and their use in therapy for treating conditions in which necroptosis is likely to play a substantial role, or those conditions in which RIP1 and/or RIP3 protein is a contributing factor, (structure shown)

Carcinogenic amines are formed in vivo during the metabolism of Sudan azo dyes. The identification and assay of these polluting agents requires the availability of deuterated analogues. Accordingly, two series of derivatives labeled on the phenylazo and naphthol moieties were synthesized. The new compounds were obtained in satisfactory chemical yields and with an excellent degree of labeling. The structures were confirmed by 1H NMR spectroscopy and high-resolution mass spectrometry.
