In some cyc1oheptanols and cyc1oheptanones, the assignments have been obtained unambiguously by the synthesis of deuterated derivatives and the use of paramagnetic-shift reagents. Substituent effects for the different types of groups have been calculated. The most informative data about the cyc10heptane conformations were provided by the relatively well understood I' effects. The results are generally in,good agreement with predictions based on the twist-chair form, which has been predicted by Hendrickson to be the most stable conformation. Pairs of cis-trans isomers are found to have rather characteristic differences in their 130 spectra. This fact was used to assign the resonances found for cis-trans mixtures of methyl-substituted cyc1oheptanols to specific isomers.}, language = {en} } @article{ChristlLechner1975, author = {Christl, Manfred and Lechner, M.}, title = {Zur intramolekularen Wechselwirkung von Cyclopropylidenen mit dem Bicyclo[1.1.0]butansystem}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-41509}, year = {1975}, abstract = {No abstract available}, language = {de} } @article{ChristlLanzendoerferFreund1981, author = {Christl, Manfred and Lanzend{\"o}rfer, Ulrike and Freund, Silke}, title = {Olefinadditionen an 2,5-Diphenyl-1,3,4-oxadiazin-6-on}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-41525}, year = {1981}, abstract = {No abstract available}, language = {de} } @article{ChristlLessMueller1994, author = {Christl, Manfred and Leß, Roland and M{\"u}ller, Heinrich}, title = {6,7-Dimethylene-2,4-diphenylbicyclo[3.2.l]oct-3-en-2-yl Anion : A Test for the Origin of the Unusual Properties of the Bicyclo[3.2.l]octa-3,6-dien-2-yl Anion}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-31547}, year = {1994}, abstract = {No abstract available}, language = {en} } @article{GigstadRicciJRMarkgrafetal.1991, author = {Gigstad, Kenneth M. and Ricci JR., John S. and Markgraf, J.
