SYNTHESIS OF SELENIUM-CONTAINING CROWN ETHERS AND RELATED COMPOUNDS

1991

Abstract The synthesis of the first examples of selenium-containing crown ethers from the benzene diselenolate anion and dichalcogenated ethers is reported. The reaction is highly dependent on the experimental conditions, particularly the concentration. 1H NMR and mass spectrometry were used to confirm the structures of the new compounds.

Formation of arynezirconocenes from substituted diaryl bis (t-butylcyclopentadienyl) zirconium: application to the synthesis of new functionalizedort…

1991

The para-substituted diphenylzirconocenes [(t-BuCp)2Zr(p-C6H4R)2; R = Br, NMe2] (A) were easily obtained from the reaction of the appropriate organolithium reagent with bis(t-butylcyclopentadienyl)zirconium dichloride. Elimination of bromobenzene or N,N-dimethylaminobenzene from A by slight heating led to arynezirconocenes into which were inserted two equivalents of elementary chalcogens. As a result dichalcogenated zirconacycles [(t-BuCp)2ZrY2C6H3R; Y = S, Se] (B) were obtained. Complexes B constitute useful potential synthons in organic synthesis and a large family of new functionalized dichalcogenated benzenic compounds was prepared by reacting electrophiles. The structure of complexes B…
