Abstract

'Diene' to know: The title reaction leads to the formation of 1,3‐dienes in high yields (see scheme). The reaction also proceeds with the use of N‐tosylhydrazone substrates. Carbopalladation to the allene and palladium carbene migratory insertion are proposed to play the key role in this transformation.
