Four tweezer-like 25,27-dihydroxy-26,28-bis(phenylselenoalkoxy)-5,11,17,23-tetra-tert-butylcalix[4 ]arenes 5-8 were synthesized for the evaluation of their ion-selectivity in ion-selective electrodes (ISEs). For investigation of the influences of the coor

Four novel rhenium(I) diseleno-ethers complexes, namely Re(CO) 3Cl(PhSe(CH2)2SePh) (5), Re(CO) 3Cl(PhSe(CH2)3SePh) (6), Re(CO) 3Cl(HO2C-CH2Se(CH2

experimental part, p. 678 - 683 (2009/10/30)
The reactivity of indium(III) benzenechalcogenolates (chalcogen = sulfur, selenium) towards organyl halides (organyl = alkyl, allyl, benzyl, acyl) was examined. A practical one-pot method to prepare organyl phenyl chalcogenides indium metal and diphenyl dichalcogenide was found. The coupling is fairly broad in scope and generally works better organyl halides capable to produce stable carbocations.

A free radical mediated ring expansion of cis- and trans-α-alkylated-β-stannylcyclohexanones to provide efficient routes to cis- and trans-cyclononenones and cyclodecenones is described.The cis-/trans- relationship in the precursor was found to have signi

A convenient synthesis of MeSeLi from MeLi and Se8 in tetrahydrofuran (THF) has been used to prepare the bis-selenoethers MeSenSeMe (n = 1,2,3,6, or 12) and cis-MeSeCH=CHSeMe.PhSenSePh (n = 1-3) and cis-PhSeCH=CHSePh have been prepared from PhSe-, itself produced from Ph2Se2 and LiALH4-THF or sodium hydroxymethanesulphinate.The bis-selenoethers o-C6H4(SeR)2 (R = Me or Ph) were obtained from R2Se2 and benzyne.The syntheses of (RSeCH2)3CMe (R = Me or Ph), (MeSeCH2)4C, and (MeSeCH2CH2CH2)2Se are also described.The 1H, 13C, and 77Se n.m.r. spectra of these selenoethers have been recorded, and the chemical shifts and coupling constants (nJSe-H, nJSe-C) are discussed in terms of structures.Mass spectra of the selenoethers have been recorded and the principle fragmentation modes identified.

A convenient procedure for phenylselenenylation of alkyl halides, alkenyl sulfonates, and epoxides with phenyl selenide anion was accomplished by electroreduction of diphenyl diselenide in a protic solvent.
