Draw a mechanism that supports the formation of the particular regiochemistry

The formation resulting from this specific regiochemistry:

Regiochemistry refers to the process that favors the creation of bonds with a certain atom over other bondable molecules. During the process, what is known as regiochemistry is responsible for explaining the regiochemical processes. 

The reaction that happens throughout the procedure is termed regioselective because the bonding atom is chosen. This approach is relevant to certain reactions, such as the addition of pi ligands. By understanding regiochemistry, we can better control the outcome of certain reactions and ultimately create more desired results.
