摘要

Abstract The palladium-catalyzed alkoxycarbonylation of aryl and heteroaryl halides using butyl formate has been investigated. In the presence of palladium (II) acetate/n-butylbis (1- adamantyl) phosphine (L1), and 1, 8-diazabicyclo [5.4. 0] undec-7-ene (DBU) as base for the first time non-activated chloroarenes can be conveniently carbonylated in good yields.
