WebDirect catalytic modifications of carbon-hydrogen (C-H) bonds, ubiquitous in organic molecules, represent a powerful strategy in organic synthesis. In the past decade, chemists have focused on the development of sustainable methods for functionalization of inert C-H bonds using cost-effective earthabundant 3d transition-metal catalysts. To fully harness … Web26 jun. 2024 · The enantioselective hydroaminocarbonylation of olefins is a straightforward method for preparing enantioenriched amides.
