It is possible that Kr and Ar could also act as Lewisbases, but evidently they cannot compete with HF.
很可能氪和氩也可以做路易斯碱，但显然它们不能和氟化氢竞争。

Under the catalysis of Lewisbases, these allylic compounds readily undergo allylic alkylations with a series of nucleophiles;
在有机路易斯碱催化下，这类烯丙基衍生物容易与亲核试剂发生烯丙基烷基化反应；

This paper introduces the complexation and dissociation of different Lewisbases with active species in the area of anionic polymerization reported in literatures and elucidates their applications.
