<i>ortho</i>‐Allylation of 2‐Arylindazoles with Vinyl Cyclic Carbonate and Diallyl Carbonate <i>via</i> Manganese‐Catalyzed C−H Bond Activation

Abstract

Abstract A manganese‐catalyzed directed C−H allylation of 2‐arylindazole has been developed. Both vinyl cyclic carbonate and diallyl carbonate are effectively used for ortho ‐allylation via decarboxylation. The mechanism was investigated and possibly Mn(I)‐catalyzed C−H bond activation is not involved in the rate‐determining step. magnified image
