Notes:
On the Umpolung of the Reactivity of a Carben Atom - Unexpected Electrophilic Addition to an η-Thiocarbene of TungstenTrifluoroacetic acid protonates the electrophilic carbene carbon atom of dicarbonyl(η5-cyclopentadienyl) [η2-methyl(methylthio)carbene]tungsten tetrafluoroborate (2) to provide the cationic tungsta-thia-cyclopropane complex 3. The 1H- and 13CNMR spectra of diastereomers 3a, 3b and the X-ray structure of 3a are described.
