Fluorinating Pyridine Appending fluorine substituents to carbon centers is commonly used to tune small-molecule properties in pharmaceutical and agrochemical research. However, fluorinations often require the use of corrosive, hazardous reagents. Fier and Hartwig (p. 956) present an unusually mild and convenient protocol for fluorinating carbon sites adjacent to nitrogen in pyridines and related nitrogen-bearing
Metal chelating compounds of formula (I) are provided: or tautomers thereof or a pharmaceutically acceptable salt of either characterised in that R1 is selected from the group H and C1-6 alkyl R2, R4 and R5 are independently selected from the group H, C1-6 alkyl, Cl, F, -CHF2, CF3, -C(O)CF3, -CH(OH)CF3 and R6 R3 is selected from the group H, C1-6 alkyl and C1-6 acyl R6 is a group -C(O)-N(R7)(R8) R7 is selected from H and C1-6 alkyl and R8 is selected from H, C1-6 alkyl and a group -CH(R9CO)-N(R10XR11 ). R9 and R10 are independently selected from H, C1-6 alkyl and C1-10 aralkyl and R11 is selected from H and C1-6 alkyl, or R10 and R11 together with the nitrogen to which they are bonded form a 3-8 membered heterocyclic ring wherein at least one of R2, R4 and R5 is F. The compounds of the invention have reduced susceptibility to glucuronidation and microsomal oxidation as compared to current clinical compounds of the same class but in preferred forms have lower molecular weight and have blood brain barrier permeability.

A series of phosphazenium hydrofluorides, P1tBu⋅[18/19F]HF, P1tOct⋅[18/19F]HF, P2Et⋅[18/19F]HF, and P4tBu⋅[18/19F]HF, was synthesized. The radioactive phosphazenium [18F]hydrofluorides were obtained by the one‐step formation and trapping of gaseous [18F]HF with the respective phosphazene bases. The [19F] isotopomers were prepared from the corresponding phosphazene bases and Et3N⋅3HF. Under the design
