Tridentate Complexes of Palladium(II) and Platinum(II) Bearing<i>bis</i>-Aryloxide Triazole Ligands: A Joint Experimental and Theoretical Investigation
novel class of palladium(II) and platinum(II) complexes bearing tridentate bis‐aryloxide triazole ligands was prepared by using straightforward and high‐yielding synthetic routes. The complexes were fully characterized and the molecular structures of four derivatives were unambigously determined by single‐crystal X‐ray diffractometric analyses. For the most promising luminescent PtII derivatives, further

O] water containing [
18
F] fluoride ions is introduced into a column packed with an ion-exchange resin to collect the [
18
F] fluoride ions and a step in which a substrate is reacted with the [

The present invention relates to a process for the preparation of 4-aminomethyl-3-alkoxyiminopyrrolidine methanesulfonate, a key intermediate of quinolone antibiotics. According to the process of the present invention, the total number of steps has been shortened to 2-3 steps, the solid separation is not required, and the use of costly chemicals, particularly (BOC)2O (t-butoxycarbonyl anhydride), several organic solvents and reactants, is eliminated.
