Conjugated dienes, e.g. 1,3-butadiene or trans, trans-2,4-hexadiene, undergo [4s + 6s] cycloaddition with tricarbonyl-η-1,3,5-cycloheptatrienechromium(0) (I) on irradiation with UV light in n-pentane at 263 K, and the bright red tricarbonyl-η-bicyclo[4.4.1]undeca-1,3,7-trienechromium(O) complexes Cr(CO)3C11H14 (II) and Cr(CO)3C13H18 (III) are formed in high yields. The structures of II and III were determined by IR, NMR and mass spectra and confirmed by an X-ray structure analysis for III.

Photo-induced chromiumcarbonyl catalyzed hydrosilylation of conjugated dienes with triethylsilane: The solvent effect
Kayran, C; Özkar, Saim; Akhmedov, VM (2003-07-01)
Photocatalytic hydrosilylation of conjugated dienes (1,3-butadiene, 2-methyl-1,3-butadiene, 2,3-dimethyl-1,3-butadiene, trans-1,3-pentadiene) with triethylsilane was studied by using Cr(CO)(5)L (L = CO, P(CH3)(3), P(OCH3)(3), P(C6H5)(3), P(C6H11)(3), NC5H5) in two very different solvents, toluene and tetrahydrofuran, for comparison with the results found in n-hexane. In toluene, the photocatalytic hydrosilylation yields the same products as those in n-hexane, with the exception of trans-1,3-pentadiene which...
Coupling of cyclopropylcarbene-chromium complex with ferrocenyl alkynes: synthesis of 5-ferrocenyl-5-hydroxy-2-cyclopentenones and 4-ferrocenyl-4-cyclopentene-1,3-diones
Zora, Metin; Bueyuekguengoer, Orhan (Elsevier BV, 2007-05-07)
The coupling of ferrocenyl alkynes with cyclopropylcarbene-chromium complex leads to ferrocenyl-substituted 2-cyclopentenones with or without a hydroxy substituent, namely 4-cyclopentene-1,3-diones, 2-cyclobutenones, and alpha, beta-unsaturated aldehydes in varying amounts. The reaction initially produces a cyclopentadienone intermediate, then to the double bond of which, bearing a ferrocenyl group, addition of water occurs to afford hydroxy-substituted 2-cyclopentenones. In all the products, the hydroxy gr...
Monodisperse nickel nanoparticles supported on SiO2 as an effective catalyst for the hydrolysis of ammonia-borane
Metin, Onder; Özkar, Saim; Sun, Shouheng (2010-09-01)
Monodisperse Ni nanoparticles (NPs) have been synthesized by the reduction of nickel(II) acetylacetonate with the borane-tributylamine complex in a mixture of oleylamine and oleic acid. These Ni NPs are an active catalyst for the hydrolysis of the ammonia-borane (AB, H3N center dot BH3) complex under ambient conditions and their activities are dependent on the chemical nature of the oxide support that they were deposited on. Among various oxides (SiO2, Al2O3, and CeO2) tested, SiO2 was found to enhance Ni N...
Photocatalytic hydrosilylation of conjugated dienes with triethylsilane in the presence of Cr(CO)(5)L(L=CO, P(CH3)(3), P(OCH3)(3))
Özkar, Saim; Kayran, C (Elsevier BV, 1997-04-15)
The effect of donor ligands on the chromium carbonyl photocatalysed hydrosilylation of 1,3-butadiene, 2-methyl-1,3-butadiene, 2,3-dimethyl-1,3-butadiene, trans-1,3-pentadiene with triethylsilane was studied. Photocatalytic hydrosilylation of dienes conducted in the presence of Cr(CO)(5)L (L = P(CH3)(3) or P(OCH3)(3)) yields the cis-1,4-adducts, 1-triethylsilyl-2-butene derivatives, as the main products; these have been isolated by distillation or preparative GC and fully characterised by NMR spectroscopy.

Synthesis of some novel derivatives of 2,6-diaminoanthraquinone dyes
Yildirir, Yilmaz; Özdemir, Melek; Disli, Ali; Çolak, Naki (2008-11-01)
In present study, some derivatives of 2,6-diaminoanthraquinone dyes are synthesized and their UV-visible spectra are investigated in various conditions. Ten compounds (la-e) and (2a-e), two of which (1a, 1b) were previously obtained in low yields, have been synthesized by using diazonium salts of 2,6-diaminoanthraquinone and characterized by spectroscopic methods.
