Significance

Vinyl ethers are prone to cationic polymerization, thus it is not easy to achieve insertion polymerization. Furthermore insertion barriers are often too high. Jordan and coworker have conducted a systematic reactivity study of various substrates with (α-diimine)PdMe+, and found that trimethylsilyl or triphenylsilyl vinyl ethers can be incorporated in the insertion copolymerization with 1-hexene. The specificity of the reaction was also demonstrated by showing that the cationic or radical route cannot produce the resulting polymer.
