Iron(III)-catalyzed regioselective direct remote C–H carboxylation of naphthyl and quinoline amides was developed using CBr4 and alcohol. The reaction involves a radical pathway using a coordination activation strategy and single electron transfer process. The use of sustainable iron catalysis, selectivity, and the substrate scope are the important practical features.
A simple and practical approach for a direct remote C-H etherification of arylamines with alcohol is developed herein by using a solid-supported Pt catalyst, hence providing a valuable method for the synthesis of aromatic ethers. The catalyst can easily be recovered from the reaction mixture and reused for six times without apparent loss of activity. Control experiments suggest that a radical pathway
An efficient protocol for cobalt (II)-catalyzed regioselective aryl C8H bond alkoxylation of 1-naphthylamine derivatives with readily available alcohols has been developed, demonstrating an efficient approach to 8-alkoxy-1-naphthylamine derivatives with good functional group tolerance. Note that the picolinamide moiety as a bidentate directing group may play a key role in this regioselective transformation
copper-mediated regioselective C–Hactivation and C–O bond formation of naphthylamides with arylboronic acids has been developed using water as an oxygen source. The kinetic isotope study suggests that C–Hbondactivation is the rate-determining step. The H2O18 labelling experiment reveals the incorporation of oxygen from water. The substrate scope, functional group diversity and post synthetic utilities are the
