The syntheses of all 16 CB11(CH3)(n)(CD3)(12-n)(center dot) radicals with 5-fold substitution symmetry are described. The variation in the width of their broad and featureless electron paramagnetic resonance signals as a function of the deuteriation pattern is used to deduce the relative values of the average hyperfine coupling constants a(H) of the hydrogen atoms in the ipso (1), ortho (2-6), meta (7-11), and para (12) methyl groups, a(H)(i):a(H)(o):a(H)(m):a(H)(p) = (0.18 +/- 0.09):(0.71 +/- 0.02):(1.00 +/- 0.03):(0.52 +/- 0.05), and these can be compared with ratios expected from a B3LYP/EPRII calculation, 0.04:0.55:1:0.51.

A new and stereospecific synthesis of an inositol analogue: bis-homoinositol
Kara, Y; Balcı, Metin (2003-03-17)
The photooxygenation of trans-8-(acetyloxy)bicyclo[4.2.0]octa-2,4-dien-7-yl acetate afforded the bicyclic endoperoxide. Reduction of the endoperoxide with thiourea followed by acetylation gave the corresponding tetraacetate. The KMnO4 oxidation of the tetraacetate followed by acetylation gave dihydroxytetraacetate Ammonolysis of tetraacetate afforded the bis-homoinositol, bicyclo[4.2.0]octane-2,3,4,5,7,8-hexol.
Reaction of pentacarbonyl(eta(2)-bis(trimethylsilyl)ethyne)tungsten(0) with tricyclohexylphosphine: X-ray structure of pentacarbonyltricyclohexylphosphinetungsten(0)
Demircan, O; Özkar, Saim; Ulku, D; Yildirim, LT (2003-12-15)
The pentacarbonyl(?(2)-bis(trimethylsilyl)ethyne)tungsten(0), W(CO)(5)(?(2)-btmse), reacts with tricyclohexylphosphine, PCy3, to yield two stable endproducts which could be isolated and fully characterized by using the single crystal X-ray diffractometry and the MS, IR, and NMR spectroscopy: W(CO)(5)(PCy3) and trans-W(CO)(4)(PCy3)(2). The former complex is the alkyne substitution product, while the latter one is formed from the conversion of its labile cis-isomer, which is generated by further reaction of t...
A new antiaromatic compound: 1,4-biphenylenequinone synthesis and trapping reactions: can a quinone unit stabilize the cyclobutadiene?
Kilic, H; Balcı, Metin (2001-12-03)
The photooxygenation of 4a,8b-dihydrobiphenylene affords an endoperoxide. NEt3-catalyzed rearrangement of this endoperoxide gave the corresponding hydroxy enone, while the CoTPP-catalyzed rearrangement afforded a bisepoxide. MnO2 oxidation of hydroxy enol leads to 4a,8b-dihydrobiphenylene-1,4-dione. The NIBS bromination of this dione produces mono- and dibromides. NEt3-supported elimination of monobromide and zinc elimination of dibromide afforded the target compound, 1,4-biphenylenequinone, which was trapp...
Challenges in line-of-balance scheduling
Arditi, David; Tokdemir, Onur Behzat; Suh, Kangsuk (American Society of Civil Engineers (ASCE), 2002-11-01)
The line-of-balance ~LOB! method of scheduling is well suited to projects that are composed of activities of a linear and repetitive nature. The objective of this study is to set down the basic principles that can be used in the development of a computerized LOB scheduling system that overcomes the problems associated with existing systems and creates solutions to problems encountered in the implementation of repetitive-unit construction. The challenges associated with LOB scheduling include developing an a...
Theoretical aspects of some 4-[2,6-substituted-9H-purin-9-yl]-2-cyclopentene-1-methanol derivatives as anti-HIV agents
Türker, Burhan Lemi; Sudagidan, M (2000-01-01)
Some (-)-(1S,4R) -4-[2-amino-6-(substituted)-9H-purin-9-yl]-2-cyclopentene-1-methanol derivatives have been considered for semiempirical treatment at the level of AM1 type calculations. Certain theoretical structure-activity relationship were investigated.
