For this alkylation type reaction, why the conversion rate dropped when further NdCl3 was introduced? And what's the rolw of NdCl3? Is it just as the LA to activate electrophile or as CeCl3 to in-situ transform the Li-type nucleophile into Nd-type?
NdCl3 absorbs water rapidly. Maybe to have a chemical balance and for chemical stability, it is added.
