The mechanism for the addition of a tosylate group to an alcohol. A tosylate group (Ts, Tos, tosyl, toluenesulfonyl) is added from tosyl chloride. It is possible to form esters as well as amides with this mechanism as well. A tosylate group can be used as a protecting group is some scenarios, however, more often it is used as a leaving group.

![Brook Rearrangement Mechanism | Organic Chemistry
Rearrangement of α-silyl oxyanions to α-silyloxy carbanions via a reversible process involving a pentacoordinate silicon intermediate is known as the [1,2]- Brook rearrangement, or [1,2]-silyl migration.
