摘要：
The combination of a Ti-salen complex with AgBArF reveals unique hard/soft heterobimetallic cooperativity in lactide ring-opening polymerisation (ROP), enabling significant activity at room temperature. Reactivity, mechanistic and computational studies highlight the role of cation-pi interactions in the formation of heterobimetallic species and provide key insights into the role of both metals in ROP.
