A complete assignment of the 1 H, 13 C and 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 1 and cis, trans ‐2,4‐hexadiene mediated by ( n 5 ‐C 5 H 5 )Mn(CO) 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 13 C‐ 1 H coupling constants and two bond 13 C‐ 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.
