Cu-catalyzed C-N bond cleavage of 3-aminoindazoles for the C-H arylation of enamines

The Cu-catalyzed C-H arylation of enamines via the oxidative C-N cleavage of 3-aminoindazoles is presented. A diverse array of arylated enamines were produced in decent yields with a wide substrate scope under mild conditions. Here, 3-aminoindazoles were harnessed as novel arylating agents via a radical process.
