Catalytic C–N and C–H Bond Activation: ortho-Allylation of Benzoic Acids with Allyl Amines
摘要:
A facile insertion of ruthenium into aromatic C-H and allylic C-N bonds are the key steps in a [Ru(p-cymene)Cl-2](2)-catalyzed ortho-C-H allylation of benzoic acids. This protocol allows drawing on the large pool of allylic amines for state-of-the-art ortho-functionalizations of arenes, turning neutral amines into leaving groups. Concise syntheses of biologically active compounds provide further evidence of the synthetic potential of this methodology.

We have succeeded in the allylation of aromatic and olefinic CâH bonds of benzoic and acrylic acids using a rhenium catalyst, Re2(CO)10. In this reaction, isomerization of the introduced allyl group to the 1-propenyl group did not occur.
