general zinc‐mediated intermolecular reductiveradical fluoroalkylsulfination of unsaturated C−C bonds has been developed using readily available fluoroalkyl bromides and 1,4‐diazabicyclo[2.2.2]octane‐bis(sulfur dioxide) adduct (DABSO) with wide substrate scope and excellent functional group tolerance. Sulfur dioxide anionradical generated in situ from the reduction of sulfur dioxide with zinc may be
Ferric nitrate with catalytic TEMPO has been identified as a useful reagent for regio- and stereoselective nitration of a wide variety of aromatic, aliphatic, and heteroaromatic olefins. This reaction provided nitroolefins in preparatively useful yields with excellent E-selectivity. Due to its mild nature and operational simplicity, the present protocol is expected to find application in synthetic setup.

The present disclosure relates generally to the administration of testosterone replacement therapy, and more particularly to a system and methods for monitoring and analyzing testosterone levels of a patient for dynamically controlling and/or managing delivery of testosterone. The system may include an implantable medical device including a pumping mechanism operatively coupled to an analyte sensor. The analyte sensor may collect a patient's testosterone levels and communicate that information to the pumping mechanism. Based on the information collected by the analyte sensor, the pumping mechanism may deliver one or more testosterone replacement drug therapies to the patient. Advantageously, the system may automatically regulate the delivery of said one or more testosterone replacement drug therapies based on a testosterone level of the patient, while minimizing patient oversight of the administration process and reducing discomfort.
