Nitration of N-ethoxy~arbonyl-[U-~~C]aniline with two equivalents of nitric acid in sulfuric acid afforded N-ethoxycarbonyl-2,4-dinitro-[U-l4C]aniline which was deprotected quantitatively to P,Cdinitro-[U-l4C]aniline. Selective hydrogenation provided 99.5% radiochemically pure [U-I 4C]nitrophenylene
Friedel-Crafts acylation of [U-14C]pdichlorobenzene with 3,6-dichloro hthalic anhydride in aluminum bromide melt followed by oleum cyclization afforded [U-p4C]-1 ,4,5,8-tetrachloroanthraquinone. Potassium fluoride mediated amidosulfonation followed by hydrolysis gave [U-14C]-1,4,5,8-tetraaminoanthra
