The Bianconeri are finalising negotiations with the Argentine defender, who will arrive on a free transfer.
Boca went to great lengths to try and keep Molina, but he will be moving to Europe for the first time in his career.
In the 2019-20 season, Molina played 16 games in Argentina’s Primera División, scoring once and assisting three goals.
The former Argentine U-20 international will replace Jens Stryger Larsen, who is expected to leave Udinese after three seasons.
Bologna are one of the clubs to have made contact for Denmark international Larsen.
Over three months later, Udinese have confirmed the signing of Molina.
