Abstract: Abstract A copper-catalyzed tandem cyclization and vinylation of 2-chloro-1-(2-bromoaryl)-3,3,3-trifluoropropenes with KOH has been developed for the synthesis of 2-trifluoromethyl benzofuran derivatives. The reaction involves dual C O bonds formation and hydroarylation of aryl trifluoropropynes. This…

Abstract: A copper(II)-catalyzed, high-efficiency and atom-economical synthesis of valuable organophosphorus compounds via tandem cyclization of o-alkynylphenyl isothiocyanates with phosphites is described. This protocol, having a good functional-group compatibility, provides a simple and direct pathway to organophosphorus…

Abstract: A novel, I2-mediated tandem cyclization of o-alkynylphenyl isothiocyanates with organophosphorus esters has been developed under mild conditions. Different kinds of 4H-benzo[d][1,3]thiazin-2-ylphosphonate could be synthesized in moderate to excellent yields. This method has the advantages of…
