Selective Protonation at a C−F Bond in the Presence of an Iridium−Methyl Bond Gives Diastereoselective Carbon−Fluorine Bond Activation and Carbon−Carbon Bond Formation. A New Path to Carbon Stereocenters Bearing Fluorine Atoms
摘要:
Reaction of iridium-fluoroalkyl complexes with fluoride acceptors occurs with completely diastereoselective activation of a C-F bond and formation of a new C-C bond. Protonation occurs with complete selectivity at the C-F bond without any detectable formation of methane by protonation at the Ir-CH3 group.
