The first general synthesis of branched tetraenes ([4] dendralenes) involves two or three
steps from inexpensive, commodity chemicals. It involves an unprecedented variation on …

A palladium-catalyzed coupling of allenylphosphine oxides with N-tosylhydrazones, leading
to phosphinyl [3] dendralenes, is established. The coupling reaction can be catalyzed by bis …

Conspectus The two simplest branched acyclic structures comprising only conjugated C C
