(Phenyltelluro)ethene (2a, 78percent) and -ethyne (4, 51percent) were synthesized for the first time.By lithiation with bulky lithium amides (lithium 2,2,6,6-tetramethylpiperidide and lithium dicyclohexylamide) 1-lithio-1-(phenyltelluro)ethene (2b) was obtained from 2a (ca. 50percent yield). 2b reacts with benzaldehyde and chlorotrimethylsilane to give the expected products 2c (88percent) and 2e (80percent), respectively, but no reaction occurred with 1-iodopropane and allyl bromide.
