The Introduction of Polarity Reversal Ketyl Strategy into Polymer Chemistry

The introduction of polarity reversal ketyl strategy into polymer chemistry to realize self-condensing ketyl polymerization triggered by electron resonance, enabling reversed polymerizability toward C-F and C-CF3 activation-cleavage polymerization.

(A) Previous work of the Barbier reaction involving challenging C-F or C-CF3.

(B) Polarity reversal strategy via self-condensing ketyl polymerization in this work.
