摘要

Abstract Heterogeneous palladium catalysts ([Pd (NH 3) 4] 2+/NaY and [Pd]/SBA-15) were applied to the synthesis of 2-functionalised indoles, giving generally high conversions and selectivities (> 89% yield) using only 1 mol%[Pd]-catalyst under standard reaction conditions (polar solvent, 80 C). For the synthesis of 2, 3-functionalised indoles by cross-coupling arylation, the [Pd]/SBA-15 catalyst was found to be particularly interesting, producing the ...
