摘要：
(p-Methoxyphenyl)tellurium trichloride reacts with terminal acetylenes to give 1-chloro-1-organyl-2-[dichloro(p-methoxyphenyl)telluro]ethenes of Z configuration in good yields. The Z stereochemistry of the addition products suggests that the reaction occurs through a four-centered cyclic transition state. The diorganotellurium dichlorides are reduced to the corresponding tellurides with sodium borohydride.
