New Reagents, XXVI. (Phenyltelluro)ethene, 1-Lithio-1-(phenyltelluro)ethene, and (Phenyltelluro)ethyne, Synthesis and Reactions(Phenyltelluro)ethene (2a, 78%) and -ethyne (4, 51%) 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 (≍50% yield). 2b reacts with benzaldehyde and chlorotrimethylsilane to give the expected products 2c (88%) and 2e (80%), respectively, but no reaction occurred with 1-iodopropane and allyl bromide.
Notes:
Erstmals wurden (Phenyltelluro)ethen (2a; 78%) und -ethin (4; 51%) synthetisiert. 2a konnte durch sperrige Lithiumamide (Lithium-2,2,6,6-tetramethylpiperidid und Lithium-dicyclohexyl-amid) zu 1-Lithio-1-(phenyltelluro)ethen (2b) (≍50% Ausbeute) lithiiert werden, das mit Benzaldehyd und Chlortrimethylsilan zu den erwarteten Produkten 2c (88%) bzw. 2e (80%) reagiert. Mit 1-Iodpropan und Allylbromid erfolgte keine Reaktion.
