论文部分内容阅读
Alkaline earth metals are readily available and inexpensive,but catalytic applications are still relatively rare in the literature.1,2 Their complexes have been employed in various applications such as ring-opening polymerization (ROP) of cyclic esters,3-5 hydroamination,6 polymerization of styrene and dienes,7 terminal alkyne coupling,8 hydrogenation,9 and pyridine activation.
