Butadiene and methanol were telomerised in the presence of palladium catalysts with ligands containing 8‐diphenylphosphinochromane‐like substituents at phosphorus. MonoXantphos and monoSPANphos afforded the most active, stable and selective catalysts known to date under commercially relevant production conditions for 1‐methoxyocta‐2,7‐diene, the precursor to oct‐1‐ene.
