The question whether steric3 or polar 4 effects control the course of E2 reactions in open-chain systems was discussed ardently during past decades and opposing views (Brown-Ingold controversy) remained irreconciled5. Our discovery that E2 reactions do not always proceed homogeneously by the anti-me
## Abstract **Summary:** Homopolymerization of 4‐methyl‐1,3‐pentadiene (MP) and copolymerization of 4‐methyl‐1,3‐pentadiene with alkenes (ethylene, 1‐pentene, 4‐methyl‐1‐pentene) were performed to investigate the effect of the so‐called backbiting coordination on the chemoselectivity of 1,3‐diene p
