polystyrene resin is described. Starting from an o‐iodobenzylalcohol with a pendant azido group, the corresponding supported complex was carbonylated with [13C]CO to produce the desired 13C‐labeled lactone tag with a satisfactory yield of 50%. This 13C‐synthon was obtained with excellent purity after a simple filtration on sintered glass, and further conjugation using CuAAC and SPAAC reactions was performed

The present invention relates to compositions and methods for sorbing (e.g., adsorption and chemisorption) and destroying organophosphate chemical agents. In certain embodiments, the invention contemplates the use of finely divided, modified nanoscale metal oxide particles. In one embodiment, a suspension of magnetite (Fe

) nanoparticles modified with 2-pralidoxime or its polymeric analog, poly(4-vinylpyridine-N-phenacyloxime-co-acrylic acid), catalyzes the hydrolysis of organophosphate compounds at a neutral pH. The oxime-modified magnetite particles serve as a nano-sized particulate carrier with a powerful α-nucleophile, an oximate group, immobilized on its surface. The oxime-modified magnetite nanoparticles are colloidally stable at neutral pH and they are readily recovered from the aqueous milieu by high-gradient magnetic separation methods.
