The presence of R1Se-F intermediates is confirmed by addition to acetylenes (4-octyne, 3-hexyne). Thus, the fluoroselenenylation of acetylenes gives fluoro(organylseleno)olefins in preparative yields. In the cases of E = Si, Ge, Sn, and Pb, aryl and n-alkyl groups are suitable as the substituent R1. The X-ray crystal structural analysis of (E)-3- (p-carboxyphenylseleno)-4-fluorohex-3-ene - the first example of an uncharged fluoroselenoolefin synthesized from p- EtO2C-C6H4-Se-SnMe3, XeF2, and 3-hexyne followed by an ester hydrolysis - shows that the addition of the selenenylfluoride intermediate to the acetylene proceeds via a trans-addition, as is known for the R2Se2-XeF2 reagents.}, language = {en} } @article{KammKammKromusetal.2000, author = {Kamm, Birgit and Kamm, Michael and Kromus, Stefan and Narodoslawsky, Michael}, title = {Green Biorefinery - European Network for the Implementation of Biorefineries (NIB)}, year = {2000}, language = {en} } @article{SchoberLoehmannsroeben2000, author = {Schober, Lars and L{\"o}hmannsr{\"o}ben, Hans-Gerd}, title = {Determination of optical parameters for light penetration in particulate materials and soils with diffuse reflectance (DR) spectroscopy}, year = {2000}, language = {en} } @article{KalliesKunzKlausetal.2000, author = {Kallies, Bernd and Kunz, Iris and Klaus, Susanne and Schorr, Ulrike and Sharma, Arya M.}, title = {Kinetic analysis of the thermic effect of food and its relationship to body composition in humans}, year = {2000}, abstract = {The course of energy expenditure after a meal can vary widely with regard to the slope of onset, amplitude, and duration of the thermic effect. The aim of the present study was to explore the relationship between the thermic effect of food (TEF), as characterized by kinetic analysis of postprandial energy expenditure, body composition, and variables related to the metabolic syndrome including central obesity, hypertension, and glucose tolerance. A total of 181 men and women (body mass index [BMI] range, 19.4 to 52.2 kg/m2) were characterized for body composition, blood pressure, oral glucose tolerance, and energy expenditure after a test meal. Energy expenditure, as measured by indirect calorimetry, was analyzed over a 6-hour period by 3-parameter curve fitting using equations derived from kinetics describing a biphasic reaction involving 2 consecutive first-order reactions (A->B->C). Apart from total thermic effect of food (TEFk), the curve also provided an estimate of time of peak (Tp) and amplitude of peak (Ap) for each subject. Multiple stepwise regression analysis with TEFk, Ap, and Tp as dependent variables showed significant effects of sex, age, body weight, body fat, -blockade, and body composition on TEF curve parameters. Cluster analysis based on Tp shown 2 distinct clusters with significant differences in age and body fat mass. This study shows that kinetic analysis of postprandial energy expenditure can be used to examine the determinants of the time course of the thermic effect of food in man.}, language = {en} } @article{LinkerEngelhardtSarkar2000, author = {Linker, Torsten and Engelhardt, Ulrike and Sarkar, Arunkanti}, title = {Kinetic resolution by Jacobsen epoxidation as an easy route to podophyllotoxin analoga}, year = {2000}, language = {en} } @article{LinkerLinker2000, author = {Linker, Torsten and Linker, Ursula}, title = {Simple synthesis of tetra-acceptor-substituted alkenes by the formal dehydrodimerization of malonates}, year = {2000}, language = {en} } @article{Linker2000, author = {Linker, Torsten}, title = {Radicals and Radical Reactions}, year = {2000}, language = {en} } @article{BeckerPeterPoolZobel2000, author = {Becker, Thomas W. and Peter, Martin G. and Pool-Zobel, Beatrice L.}, title = {Cellular effects of lignans : modulation of growth, oxidative DNA damage and cell metabolism in human colon cancer cells}, year = {2000}, language = {en} } @article{StruszczykLothPeter2000, author = {Struszczyk, Marcin Henryk and Loth, Fritz and Peter, Martin G.}, title = {Properties of microcrystalline chitosan gel-like dispersion and formed films}, year = {2000}, language = {en} } @article{KumkeSpechtFrimmel2000, author = {Kumke, Michael Uwe and Specht, C.
