The ability of a silyl group to stabilize a carbocation β to silicon, the β-effect, is directly related to the electron-withdrawing ability of the groups on silicon.This was shown by using the degree of syn addition of bromine to (E)-β-silylstyrenes as a

An Examination of the β-Effect in an Addition Reaction with Different Ligands on Silicon
The degree of cis-addition of bromine to a series of β-silylstyrenes may be used to compare the ability of silicon atoms bearing a variety of different ligands to stabilize a β-carbocation.
