propargylic esters leading to unsymmetricallysubstituted naphthalenes has been developed. This cascade reaction involves an unprecedented tandem sequence of 1,3- and 1,2-migration of two different migrating groups. It is believed that this transformation likely proceeds via the formation of 1,3-diene intermediate or its precursor, which upon cyclization and aromatization steps transforms into the naphthalene

The palladium catalyzed annulation of 1‐bromo‐2‐vinylbenzene derivatives with internal alkynes was realized for the efficient synthesis of substitutednaphthalenes. A controllable aryl to vinylic 1,4‐palladium migration process is the key for success.
