- 中文摘要: A complete assignment of the /sup 1/H, /sup 13/C and/sup 19/F NMR spectra of 1,1,4,4-tetrafluoro-2-propylidene-3-methyl-6-tert-butyl-1,4-disila-5- cyclohexene 3, the product of the cycloaddition reaction between tetrafluorodisilacyclobutene and cis, trans-2,4-hexadiene mediated by(.eta./sup 5/-C/sub 5/H/sub 5/)Mn(CO)/sub 3/, has been made by means of various 2D NMR chemical shift correlation methods and selective heteronuclear decoupling techniques. An analysis of the three bond /sup 13/C-/sup 1 /H coupling constants and two bond /sup 13/C-/sup 19/F coupling constants and the molecular modeling results enabled the determination of the conformation and configuration of compound 3. The conformation of 3 provides insight into mechanistic details of the Mn-mediated cycloaddition.
