By carrying out density functional theory (DFT) calculations, we have performed a detailed mechanism study on the Pt(II)-catalyzed tandem migration reactions of propargylic carboxylates. Our calculated results suggest that the 1,2-H migration and 1,2-allyl migration are the key paths for the reaction of 4-(allyloxy)-1,4-diphenylbut-2-ynyl acetate (1A), and the 1,2-H migration path is favored. For...
