Default Lithium bromide vs Sodium Bromide



Generally, solubility and Lewis acidity. I remember some work out of IU
about 20 years ago that used something like 30 % LiClO4 in ether as a
reaction medium to accelerate Diels-Alder reactions. I was mostly impressed
how soluble it is. Lewis acidity helps accelerate reactions like Sn2
displacements by tugging on the leaving group while the nucleophile pushes
from the other side.
