 Title    Preparation of Spin-Labeled Phosphoroamidates in High Yield Using Imidazole as the Transfer Agent  
 Abstract    The spin-labeled (l-oxyl-2,2,6,6-tetramethyl-4-piperidyl)-phenyl imidazole-1-phos-phonate (4) was used to prepare (l-oxyl-2,2,6,6-tetramethyl-4-piperidyl)phenyl N-alkyl and N-aryl phosphoroamidates (8) in yields generally exceeding 70%. @ > -0 -P -N R 'R " ^ -0 -P -C I OR OR OR 4 8 1 0 Amidates 8 were also prepared from the corresponding chloridate 10. However, in the

 Title    Investigation of Inductive Effects on the Transphosphorylation Reaction of Spin-Labeled Phosphoryl Imidazolides, Part  
 Abstract    Spin-labeled phosphoryl imidazolides 3, 6 , and 7 were prepared and compared to the unsubstituted compound 1 in reactivity towards hydroxy and amino compounds. The transphorphorylation reaction of compounds 3 and 6 was slower than that of 1. The reaction of compound 6 was selective towards amines since no reaction occurred with hydroxy compounds. The reaction of compounds 7 was slow with hydroxy compounds and rapid with amines at room temperature. The transphorphorylation reaction of 1 was rapid with both hydroxy and amino compounds at 50-55 °C.
