Versuchsvorschrift

Thiofenchone (23 mg, 0.14 mmol) was reacted with bis-(p-methoxyphenyl)telluroxide for 42 h. Fenchone (5 mg, 23%) νmax 1965,1930,1875,1742,1465,1385 and 1025 cm-1 was obtained after p.l.c. (petroleum ether-ethyl acetate 20:1). A low yield was obtained due to volatility of the product. Sulphur and bis-(p-methoxyphenyl)telluride were, however, isolated in 75 and 81% yields respectively.
