Generation of ferrocenylvinyl cation CpFeC5H4–C+=CH2 by protonation of ferrocenylacetylene with Nafion and its reactions with SMe2 and PPh3 in scCO2 giving onium salts

Add time:07/14/2019    Source:sciencedirect.com

Cation CpFeC5H4–C+=CH2 was obtained by protonation of FcCCH with Nafion superacid in DMF or scCO2 and characterized by NMR spectroscopy. The protonation in the presence of SMe2 or PPh3 affords new onium derivatives, which were isolated as the tetrafluoroborate salts.
