Phenylhydrazine → Benzene, 1,1'-tellurobis[4-methoxy-

Participants

Reaction Steps

Phenylhydrazine (121 mg, 1.12 mmol) was reacted with bis-(p-methoxyphenyl)-telluroxide for 0.2 h. to yield benzene (53%), p.l.c. (benzene-petroleum ether 2.8) afforded bis-(p-methoxyphenyl)-telluride (262 mg, 68%) and phenyl-p-methoxyphenyl-telluride (101 mg, 29%) m.p. 59°-62°. The latter on recrystallisation from methanol gave white needles, m.p. 61°-62° (lit., 60.5-61.5), δ(CDCl3) 7.63 (d, J 8 Hz), 7.72-7.00 (m), 6.70 (d, j 8 Hz) combined integral 9H and 3.73 (3H, S), m/e 314(+), 184(100%) 169, 141 and 77 (Found: C, 50.03; H, 3.86 Calc. for C13H12O Te: C, 50.07; H, 3.88%).
