- Item(μ5-Cyclo-penta-dien-yl)bis-(triphenyl-phosphane)cobalt(I) -toluene-n-hexane (1/0.20/0.25)(Chester : International Union of Crystallography, 2008) Hapke, M.; Spannenberg, A.The title compound, [Co(C5H5)(C18H15P)2]·0.2C7H8·0.25C6H14, was synthesized by the reaction of cobaltocene, Cp2Co, with elemental lithium in tetra-hydro-furan in the presence of two equivalents of PPh3. The mol-ecular structure displays a cobalt(I) center in a distorted trigonal-planar coordination environment, with one Cp and two phosphane ligands. There are two crystallographically independent mol-ecules in the asymmetric unit besides the disordered solvent molecules.
- ItemPyrimidine acyclo-C-nucleosides by ring transformations of 2-formyl-L-arabinal(Basel : MDPI, 2005) Bari, A.; Feist, H.; Michalik, M.; Peseke, K.The protected 2-formyl-L-arabinal 2 reacted with thiourea and cyanamide in the presence of sodium hydride to afford via ring transformations the 5-[1R,2S-1,2-bis(benzyloxy)-3-hydroxypropyl]-1,2-dihydropyrimidines 3 and 4, respectively. Similarly, treatment of 2 with 3-amino-2H-1,2,4-triazole yielded 6-[1R,25-1,2-bis(benzyloxy)-3-hydroxypropyl][1,2,4]-triazolo[1,5-a]pyrimidine(5) .
- ItemAn 8-fold parallel reactor system for combinatorial catalysis research(New York : Hindawi, 2006) Stoll, N.; Allwardt, A.; Dingerdissen, U.; Thurow, K.Increasing economic globalization and mounting time and cost pressure on the development of new raw materials for the chemical industry as well as materials and environmental engineering constantly raise the demands on technologies to be used. Parallelization, miniaturization, and automation are the main concepts involved in increasing the rate of chemical and biological experimentation. Copyright © 2006 Norbert Stoll et al.
