AbstractΓUpon reaction with enol ethers a-exo-methylene-2-oxacyclopentylidene complexes of chromium and tungsten 3 and 4 undergo [212]cycloaddition under mild thermal conditions to give spirocyclobutanes 5Β±12 in good yields as single diastereomers. The relative stereochemistry (as established by X-r

the line-shape changes allow the detection of two different dynamic processes, which may be assigned to inhibited rotations about the partial C C and C N double bonds of the E-isomers (Scheme 2). Above ca. 0Β°C conversion into the isomer with Z-configurated CC double bond, which contains an intramol
