One ketyl radical anion can enable a 3–3 coupling reaction, radical polymerization at a carbon radical site, and anionic ring-opening polymerization at an oxygen anion site. This results in simultaneous organic synthesis and polymerization in one pot; thereby cyclopentane derivates and polymers with low Đ are successfully prepared under mild conditions.

羰基阴离子介导的自由基聚合和阴离子开环聚合得到低分子量分布的聚合物

一个羰基阴离子可以进行3-3偶联反应，在碳自由基位点进行自由基聚合，在氧阴离子位点进行阴离子开环聚合。这导致有机合成和聚合在一锅中同时进行；从而在温和条件下成功制备出低Đ的环戊烷衍生物和聚合物。
