Ru-catalyzed pyridyl-directed C–H allylation of arenes with allylicamines has been developed. This reaction was carried out in the presence of 5 mol% of [Ru(p-cymene)Cl2]2 and 0.5 equiv. of AgOAc in CF3CH2OH at 75 °C, affording the allylated products of arenes in moderate to excellent yields. The method exhibits a wide scope of allylicamines and arenes and shows a good compatibility of functional groups
Versatile cobalt-catalyzed C-H allylations on arenes, indoles, and pyrroles were accomplished with allyl acetates. The C-H/C-O functionalization process was characterized by a broad substrate scope as well as an excellent functional-group tolerance and was shown to occur by initial C-H cobaltation.
