Expedient cobalt(ii)-catalyzed site-selective C7-arylation of indolines with arylboronic acids†
Abstract
Cobalt(II)-catalyzed pyrimidyl directing group-assisted C7 arylation of indolines with arylboronic acids has been developed using Mn(OAc)2·4H2O as an oxidant. The use of cobalt(II)–PCy3 as a catalyst and broad substrate scope are the important practical features.
