Abstract
Benzene oxide ‐[U‐^14^C] was prepared from benzene ‐(U‐^14^C) by modifications of methods described for the inactive compound.
Benzene oxide‐[3.6–^3^H] was prepared by decomposition of 3.6‐bis‐trimethylsilyl‐1,4‐cyclohexadiene with tritiated water. bromination of the 1,4‐cyclohexadiene‐[3,6‐^3^H] so obtained. epoxidation and dehydrobromination.
With the latter method benzene oxide‐[3,6–^3^H] can be prepared at a much lower cost and higher specific activity than benzene oxide‐[U‐^14^C].
