✦ Synopsis

is removed with concentrated hydrochloric acid. Distillation of the organic phase affords 13.1 g (14%) of ( 2), b.p. 31 OC/O.02 mm, yellow needles, m.p. 49 "C from methanol. It has A, , , = 295 mp, log E = 4.05 in cyclohexane, and infrared absorptions at 695 (m), 805 (s), 1000 (m), 1230 (s), and 1490 (m) cm-1 121. The new compound readily absorbs 1 mole ofchlorine, being converted quantitatively into hexachlorotellurophene (3), bright yellow crystals, m. p. 200 "C. When a suspension of (3) using N M R methods [1,2]. The values obtained for p e ~ were 4.5 B.M. for ( I ) , 10.6 B. M. for (2), and 10.1 B. M. for (3).
