Abstract
(U‐^14^C) Phenol and isobutene under pressure in presence of aluminium phenoxide gave in 60 % yield a mixture of (ring U‐^14^C) 2‐t‐butylphenol (50 %) and (ring U‐^14^C)‐2,6‐di‐t‐butylphenol (10 %) which were separated by column chromatography on silicagel. Each t‐butylphenol was nitrated under appropriate conditions to give an 35 % overall yield of (ring‐U‐^14^C)‐4,6‐dinitro‐2‐t‐butylphenol : specific activity : 27.4 mCi/mMol which was proved by TLC and HPLC to be 99 % radiochemically pure.
