Due to the favourable properties of fluorine, approximately one fifth of newly registered small drugmolecules are organofluorine compounds. Moreover, the artificial isotope F (t1/2 109.8 min) has suitable nuclear properties for in vivo imaging in human subjects using positron emission tomography (PET). Hence, there is a large demand for efficient fluorination methodologies in both medicinal and...

Three-dimensional organic microfabrication, an emerging technology, faces the challenge of lacking a sacrificial agent (SA) to temporarily support the formation of microscale geometries, which can be removed after a microstructure is constructed. In this study, an ultradense oil-in-organofluorine colloidal emulsion with photopolymerizable submicrometer droplets (diameter approximately 500 nm) w...

Etoxazole, 2-(2,6-difluorophenyl-4-[4-(1,1-dimethylethyl)-2-ethoxy-phenyl]-4,5-dihydrooxazole, an organofluorine chitin synthesis inhibitor, was assayed for its bioactivities against several major insect and acarus pests and compared to several other pesticides: two chitin synthesis inhibitors, hexaflumuron and chlorfluazuron; a pyrethroid, permethrin; an organophosphate, acephate; a carboximid...

Fluorine substituents have become a widespread and important drug component, their introduction facilitated by the development of safe and selective fluorinating agents. Organofluorine affects nearly all physical and adsorption, distribution, metabolism, and excretion properties of a lead compound. Its inductive effects are relatively well understood, enhancing bioavailability, for example, by ...

A catalysis-based regioselective 1,4-fluorofunctionalization of trifluoromethyl substituted 1,3-dienes has been developed to access compact, highly functionalized products. The process allows E,Z-mixed dienes be processed a single E-alkene isomer, and leverages an inexpensive operationally convenient I(I)/I(III) catalysis platform. first example catalytic 1,4-difluorination is disclosed subsequ...
