Rhodium-catalyzed arylative cyclization of alkynyl malonates by 1,4-rhodium(I) migration [PDF]
Chemical Communications, 2019 The synthesis of functionalized 1-tetralones by the rhodium(I)-catalyzed reaction of alkynyl malonates with arylboronic acids is described. These arylative cyclizations proceed via an alkenyl-to-aryl 1,4-Rh(I) migration as a key step. Preliminary results
