Desulphurisation-Dimerisation of Dithioacetals with W(CO)6

Dithioacetals undergo desulphurisation-dimerisation to give the corresponding dimeric alkenes in good to excellent yields on treatment with W(CO)6.

One-Electron Redox Reactions of Octaphenylradialene: Generation and ESR/ENDOR Characterisation of Its Radical Anion and Radical Cation

The cyclovoltammograms of octaphenylradialene in DMF or THF at room temperature disclose each two quasireversible reduction and oxidation potentials at -1.4 V/-1.7 V and +0.7 V/+0.9 V.Accordingly, both the radical anion and the radical cation can be ge

Mechanosynthesis of Odd-Numbered Tetraaryl[n]cumulenes

A mechanochemical synthesis of one-dimensional carbon allotrope carbyne model compounds, namely tetraaryl[n]cumulenes (n=3, 5) was realized. Central for the mechanosynthesis of the cumulenic carbon nanostructures were the development of a mechanochemical Favorskii alkynylation-type reaction and the implementation of a solvent-free, acid-free reductive elimination with tin(II) chloride by ball milling.

A Four-Step Synthesis of Substituted 5,11-Dicyano-6,12-diaryltetracenes with Enhanced Stability and High Fluorescence Emission

A four-step synthesis of substituted 5,11-dicyano-6,12-diaryltetracenes was developed, starting from readily available para-substituted benzophenones. The key step of this straightforward route is the complex cascade reaction between tetraaryl[3]cumulenes

Synthesis of cyano-substituted diaryltetracenes from tetraaryl[3]cumulenes

A versatile, two-step synthesis of highly substituted, cyano-functionalized diaryltetracenes has been developed, starting from easily accessible tetraaryl[3]cumulenes. This unprecedented transformation is initiated by [2+2] cycloaddition of tetracyanoethy

Palladium-catalyzed arylation of butadiynes

Diarylbutadiynes 1 undergo a palladium-catalyzed coupling reaction with aryl halides 2 to give tetraarylbutatrienes 3, which may further react to benzofulvenes 6 depending on the reaction temperature and the type of aryl groups. (C) 2000 Elsevier Science

Electron transfer and contact ion pair formation, 45 [1, 2] structural changes on single electron reduction of tetraphenylbutatriene to its radical anion and on twofold deprotonation of tetraphenylbutyne-2 to the tetraphenylbutatriene dianion

Tetraphenylbutatriene is reduced under aprotic conditions to its ESR/ENDOR-spectroscopically characterized radical anion and to its dianion, with both electron transfers quasi-reversible according to cyclovoltammetric measurements. The alkali cation salts

Nickel(0)-induced geminal bond cleavages leading to carbon-carbon double bonds: Intermediacy of nickel(0)-carbene complexes as a unifying hypothesis

The possibility of effecting geminal bond cleavages of organic monomers with nickel(0) complexes to achieve olefinic dimers has been investigated both in stoichiometric reactions between monomers of the type R2CE2 and R2C=E and the complexes (Cod)2Ni, (Et3P)4Ni and (Bpy)(Cod)Ni and in nickel(0)-catalytic α-elimination reactions of α-lithioorganic sulfones, RR′C(Li)(SO2R″). Substrates for the stoichiometric geminal bond cleavages comprised geminal dihalides, aminomethyl sulfides, cyclopropenes, thioketones and ketones. Reductive dimerization to the olefin or its hydroxy derivatives was found to occur to a varying degree in most cases, including the catalytic decomposition of the α-lithioorganic sulfones. Accordingly, this method offers considerable promise in organic synthesis. A gamut of known nickel(0) chemistry, results of chemical-trapping and spectroscopic evidence are marshaled in support of the proposal that such geminal bond cleavages and reductive coupling processes most likely proceed via nickel(0)-carbene intermediates of the type R2C=Ni · Ln.

Donor-Substituted Cyclobutenylidene Complexes and Cyclobutenones from Vinylidene Complexes and Electron-Rich Alkynes

Pentacarbonyl(vinylidene) complexes of chromium and tungsten, (CO)5M=C=C(R1)R2 (1) 1 = R2 = Ph (a), R1 = tBu, R2 = Et (b), Me (c); M = Cr; R1 = tBu, R2 = Me (d)> react with 1-(diethylamino)-1-propyne by regiospecific addition of the CC bond of the alkyne to the Cα=Cβ bond of the vinylidene ligand to form the cyclobutylidene complexes 2a - d.Oxidative cleavage of the cyclobutylidene ligand from 2a - d gives the corresponding cyclobutenones.The reactions of 1b with bis(diethylamino)acetylene and of 1a with 1-ethoxy-1-propyne afford the cyclobutylidene complexes 3b and 4a, respectively.In contrast, 1a reacts with diorganylcyanamides, NCNR2 (R = Me, Et, iPr), by ligand displacement and formation of the tetraphenylbutatriene and diorganylcyanamide complexes.The structures of 2c and 4a were established by X-ray analyses.
