In stark contrast with Zn or even Mg, only a handful of efficient ROP single-site initiators based on the larger alkaline-earth metals (calcium, strontium and barium) have been reported to date [1].Such paucity of well-defined Ae-based initiators (Ae =Ca, Sr, Ba) is undoubtedly related to the difficulties encountered in taming the high reactivity of these very large (rionic =1.00, 1.18 and 1.35for Ca, Sr and Ba respectively) [2] and electropositive metals.
