    Notizen: Abstract A comprehensive review of the chemistry of polyhedral cluster complexes in whichs,p,d, andf-block metals are incorporated into C2B4-carborane cages to form the respective metallacarboranes is presented. The main focus of the review is directed toward systematizing the chemistry of metallacarboranes in order to promote their use as possible electronic, ceramic, and/or catalytic materials in addition to providing information on which we can test and expand our knowledge about the fundamental interactions that are at work in determining the structures and properties of these cluster complexes.

    Ring closure of diethyl 2-methoxy-2-[N-(5-amino-1-benzylimidazolyl-4-carbonyl)amino]malonate: Product structures and pathways of product formation (1994)
    Springer
    Structural chemistry 5 (1994), S. 375-381 
    Details
    ISSN: 1572-9001
    Schlagwort(e): Imidazoles ; purines ; imidazol[4,5-e][1,4]diazepines ; X-ray crystallography

    Thema: Chemie und Pharmazie
    Notizen: Abstract Ring closure of the title compound (1) with sodium methoxide in methanol yielded three products, one 5∶6-fused and two 5∶7-fused heterocyclic systems: 9-benzyl-2-methoxycarbonylhypoxanthine (2), 3-benzyl-4,5,7,8-tetrahydro-6-methoxy-6-methoxycarbonyl-6H-imidazo[4,5-e][1,4]-diazepine-5,8-dione (3), and 3-benzyl-4,5,7,8-tetrahydro-6-methoxy-6H-imidazo[4,5-e][1,4]-diazepine-5,8-dione (4). Structures and pathways of formation of all three products have been described. Structures of2 and3 were confirmed by single-crystal X-ray diffraction analyses.
